Cory catfish egg development

Corys will lay eggs anywhere, often on the glass, but also on the gravel, around or on plants, on the filter or decorations like rocks For this reason it is often best to breed them in a tank of their own or be ready to remove all the other fish from the tank they spawn in.

It's also a good idea to have them in tank that is set up just to breed them so you can have no gravel. No gravel means you can keep the tank cleaner as you raise the fry. To keep these fish you should 1st make sure that they are is a group of at least 4, but more is good.

Also keeping them in shoals means you'll almost deffinatly have a pair. To get them to spawn make sure their water parameters pH The change in temperature will tigger spawning.

They will sometimes spawn without doing this, but this increases the chances. If they spawn in the community tank, just take out all the other fish and feed the fry once they're free swimming and make sure that you cover any filter intakes that they can get sucked into. After spawning take the adults out and start to feed the fry once their yolk sac is absorbed. Fry will take crushed quality flake, but live foods like "chopped" black worm, micro worms and baby brine shrimp are less poluting.

Scraping the eggs off glass is very delicate and rarely works. Scraping the eggs off touching them could be the reason they got fungus. Another reason they might have got fungus could be that they weren't fertile to begin with. If you want to try and hatch this second batch of eggs, I suggest you leave them where they are and try and move all the fish to other tanks. If you leave them alone and they get fungus, you will be able to determine that they weren't fertile and may need to question whether you have a pair or not.

A female will lay eggs without a male The bigger problem with raising the young in the main tank is finding them and feeding them, this is always easier in a smaller bare bottomed tank. Maybe look at keeping your corries in a seperate tank if you want to breed them. Hello guy can u tell me at which age Corys start breading. Becaus ethis species is very social it is always best to keep corys in groups of minimum This way you will always have a few pairs too.

Hi Ace, my cory question is And it looks like I can see something in the eggs with a magnifying glass.It is called Panda since it has black marking over its eyes. Black markings are also present on the dorsal fin and audal peduncle. The main body color is pink to orange. These fishes seldom grow bigger than 4. The recommended method of pairing Corydoras panda is to get a group of juveniles and let them grow up together.

Panda cats are highly sociable creatures, so getting at least specimens is recommended.

This will also increase your chances of getting at least one of each sex. If you are lucky, you will even get several males. A group consisting of several males is more prone to spawn. A 10 gallon aquarium is sufficiently large to serve as breeding aquarium for Panda catfish.

The aquarium should be well planted; you can for instance use Java moss and Amazon sword. Also give your Panda catfish at least one really sheltered place to rest in, e. If you want to raise egg and fry with their parents, ideally provide them with hiding spots by placing marbles on top of the substrate. The pH should be around neutral, but Corydoras panda tolerates everything from pH 6.

The dH range for this species is dHbut if you want them to spawn you should ideally keep it under dH A nutritious diet is imperative if you want to breed Corydoras panda. Feed your catfish a varied diet with plenty of meaty foods.

You can for instance combine black worms and brine shrimp with sinking catfish food and some high-quality flake food. Frequent water changes are even more important if you feed your catfish black worms.

During spawning, the males will follow the fertile female around and circle her.

Panda cory (Corydoras panda)

The eggs are no larger than 1. Unlike many other catfish species, Corydoras panda produce rather small batches. You can either leave the eggs with the parents or separate them from the adult fish.

If you raise the offspring away from the parents, methylene blue can be used to prevent fungi. At this point, the fry is no bigger than 6 mm and will seek out a sheltered place where they can stay until they grow bigger. It can take several weeks before they feel confident enough to swim around freely in the aquarium even if they have their own aquarium without any adult fish.

Hints of the attractive panda pattern can be seen when they are no older than two weeks. After four weeks, they will be over 1 cm long and much thicker than when they hatched. At two months of age, Corydoras panda fry are normally at least 2 cm long. When the fry hatch, they will feed from their yolk sac for another 48 hours.To submit your vote please sign in or sign upit is free and takes a few seconds.

Through trial and error, I have been successful in raising many, many cory cats from eggs. You need to have a 5-gallon cycled tank ready with heater and filter and no substrate. It is not necessary at this point to cover the intake of the filter - that comes later. In the 5-gallon tank, hang a breeder net directly across from the filter. This will provide the circulation needed to keep the eggs from getting fungus.

Corys are capable of laying eggs starting at 8 months old to one year. Of course, you must have a mated pair. The female is much larger than the male and you will notice the pair are always together in the aquarium.

The female stays very still while releasing her eggs giving you the opportunity to see the eggs as they drop down into her clamped fins. She will then swim up and down on the glass, or on a broad-leafed plant, cleaning a place to lay her eggs.

This is where your patience needs to kick in, as it can take seconds to minutes for her to pick the right spot. My corys usually lay their eggs in the early morning, and timing on your part is everything - you have to see the corys laying eggs to have any chance of saving them.

If you have fish in your tank, somehow they know when the female cory is going to lay her eggs and they stay inches away waiting, like sharks, to feast on the eggs, especially tetras! I have actually had to keep my hand in the tank to keep the tetra away! Adult corys will also eat the eggs if given the chance. Once the eggs are laid, the cory pair swim away and will go through the chasing and the T-formation again and again until the female has laid all of her eggs.

It can take anywhere from 1 minute to 15 minutes for the female to lay eggs each time. During this time, you need to rescue the eggs. She will lay 2 to 10 eggs each time, but this can and does vary.

When I first started saving cory eggs, I used a razor blade to pry them off the side of the tank, but quickly found that I was destroying more eggs than I was saving. Do this gently and slowly! You may crush one or you may drop one until you get the hang of it. I then gently roll the eggs from my fingers onto leaves I cut off of a plastic plant, placing eggs on each leaf. You should have these cut and ready to use beforehand.

Place the leaf in the breeder net with the eggs facing DOWN. The eggs will hatch within days and the babies will look like two eyeballs with a tail. Starting on the second day, offer them powdered fry food and continue with this food until they are released into the 5-gallon tank, usually at about 6 or 7 weeks old. At about 4 weeks old, you can drop half of a Hikari Sinking Algae Wafer in the net and also offer them baby flake food. To transfer the babies from the net to the tank, use a small tightly woven fish net.Corydoras panda is a species of catfish belonging to the genus Corydorasof the family Callichthyidaeand is a native member of the riverine fauna of South America.

The species was first collected by Randolph H. The specific name is an allusion to the appearance of the fish, which possesses large black patches surrounding the eyes, reminiscent of those found on the giant panda.

Accordingly, the common names for this fish, which is a popular aquarium species, are panda corydoras and panda catfish. Corydoras panda has an off-white to pinkish-orange ground colour, and when observed under certain lighting conditions, a faint greenish iridescence is present upon the flanks and the operculum.

The fins of the fish match the body in ground colour, upon close inspection being seen to be hyaline or translucent with coloured fin rays, with the dorsal fin being marked by a conspicuous black blotch that covers almost the entire fin area. The caudal peduncle is marked with a black band, this black band encircling the caudal peduncle from dorsal to ventral surface.

The adipose finsupported by a small fin spine, sometimes contains black pigmentation. The head is the same ground colour as the body, with a black mask surrounding the eyes, descending vertically from the fontanelover each eye, and ending in a triangular wedge immediately before the ventral surface of the head.

The pectoral fins are positioned immediately behind the operculum, and are usually oriented horizontally when the fish is at rest, extended in a manner similar to the wings of an aeroplane. The pelvic fins are positioned upon the ventral surface of the fish, located some way behind the pectoral fins. The first ray of the dorsal fin emanates from the body at approximately its point of greatest elevation, and a vertical line drawn downwards from this point meets the attachment point of the pelvic fins.

The anal fin is located far to the rear of the ventral surface of the body, the attachment point of the first fin ray being somewhat forward of the black caudal peduncle marking described above. In common with all other members of the family Callichthyidae, the body surface is covered, not with scalesbut with bony plates known as scutes. The lines of demarcation between individual scutes can be seen upon close examination of this and almost all other Callichthyid fishes, and in the case of some specimens of this species, are highlighted by additional black pigment.

The fish possesses, in common with almost all Corydoras species, three pairs of barbels —one pair of maxillary barbels and two pairs of rictal barbels. A fully mature adult specimen of this species attains a standard length of 55 millimetres 2. Corydoras panda inhabits clear river waters that are relatively fast-flowing, well-oxygenated, and flowing over substrates that may comprise soft sand or fine gravel.

These rivers are usually well vegetated with assorted species of aquatic plants. The native waters of Corydoras panda are consequently mineral-deficient, with a neutral to slightly acid pH, and replication of such conditions in captivity are recommended for successful maintenance.

Corydoras panda has a preference for cooler than normal waters when compared to many other popular tropical fish species. Because of this, those who keep C. Additionally, scrupulous attention to aquarium substrate cleanliness is a must, as the fish are intolerant of poor aquarium maintenance in this area, and succumb to stress and disease rapidly if their aquaria are not kept to a high standard. Despite this, the species remains highly popular with aquarists, upon account of the appearance of the fish, and its lively, vivacious behaviour in a well-planned aquarium setting.

Like many other Corydoras species, the panda catfish is a highly gregarious fish, and in common with several other smaller Corydoras species such as C. A minimum of eight individuals should be housed in the same aquarium, and if space permits, this number should be revised upwards, as the fish exhibits a very definite preference for grouping together with others of its species.

They also associate themselves easily with the clown loach and school together in currents where sufficient numbers of their own species is lacking. An aquarium for this species should be well furnished, ideally with a mixture of live aquatic plants, and solid furnishings providing caves, sheltered areas and hiding places to give the fish security. Floating plants to provide additional areas of shade are also welcomed by the fish.

Like all Corydoras species, the fish feeds primarily upon animal matter.

The aquarist is advised, however, that the traditional use of Corydoras catfishes as putative 'scavengers' in an aquarium setting will be detrimental to the well-being of this species—it requires high quality foods for long-term maintenance, and a varied diet. Ideally, the fish should be given live foods at least intermittently, and will dine enthusiastically upon such items as Bloodworms larvae of Chironomus midgesDaphniacultivated Brine Shrimp Atermia salinaand Tubifex worms.

The last, however, should be cultivated in order to minimise the risk of introducing pathogenic organisms to the aquarium, as Tubifex live in unsanitary conditions in the wild.

Freeze dried Tubifex may be preferable, as the risk of introduction of disease is eliminated. High quality flake foods are also appreciated, particularly those containing shrimp or other similar matter. The lifespan of Corydoras panda in the aquarium has not been systematically determined, but given the longevity of other Corydoras species in the aquarium, it is reasonable to assume that well-cared for specimens will enjoy a lifespan in excess of ten years, and frequently in excess of 15 years.Cory Catfish are peaceful, easy to care for and often, one of the first fish that an enthusiast will get.

Often found in shoals in large community tanks, they are beautiful additions that bring personality to the lower levels of the tank. There are over species of these small fish, but before we get into the ins and outs of how to care for them, here is a simple table to help you decide if these are the fish for you.

Cory Catfish are famously peaceful, and as they live at the bottom of the tank most of the time they can live out their own lives without interference. They belong to the genus Corydoras, a group of over described species of Catfish from South America. The best specimen should not be thin, as catfish Corydoras should be a little plump and have clear colorations and patterns.

They are bottom-dwelling and like to hide or rest during the day, but in the evening will shoal with other fish. You will only see them leave the bottom of the tank when they dart to the surface in order to get some air.

This behavior was adapted so they could survive in waters with lower oxygen levels but they still occasionally do this even in good conditions. If the behavior seems frequent, the introduction of plants or an air stone can provide them with more oxygen. All species are very peaceful and will not attack their tank mates, they will also hide when threatened. This makes them easy to pair with most community fish more on this later.

However, some species are venomous and if highly stressed they can produce toxins that can kill everything in the tank. This means they should be transported on their own and removed from the tank if they appear stressed and promptly placed into quarantine.

Cory catfish are armored, with a short face and a flat underside. They have pectoral fins that stick out and rest on the surface, often propping themselves up with them. Their dorsal fins point upwards like a sail, but some varieties have more rounded fins.

The tail fin is most commonly forked, but the length and height also vary between species. Like other Catfishthey have three pairs of barbels on their face which are used to detect food in the sand. Many species have colors that allow them to blend into the browns of the riverbed, but some are pale such as albinos or shimmering like the emerald Cory Catfish.Cory Catfish are peaceful, easy to care for and often, one of the first fish that an enthusiast will get.

Corys are small fish, with most species around 2. The smallest ones are just over an inch and the largest is 4 inches long. A variety developed from the Peppered Cory, these fish are a pinkish white with red eyes that almost glow. They are only available from breeders as they are not a wild species.

Named because of the black patches around their eyes, they also have a base color of white or orange, that reflects some green. They prefer cooler waters and demand a higher quality of maintenance because their native rivers have mountain streams and meltwaters from mountain snow flowing into them.

These medium-sized Corydoras are available in four different colors: green, bronzeblack and albino. They are active in the aquarium, but often shy compared to other Corys.

They are easy to care for and are also attractive and very peaceful. They are bronze with black patches across their body — long-finned or albino varieties are also available. The smallest of the Corydoras, they will remain at around 1 inch long. They will need feeding smaller foods and do better with dimmer lighting. It cannot be paired with larger fish and should be given lots of hiding places. Sharp barbels under their eyes and in front of their dorsal fins, and the ability to move their eyes in a way that seems like winking, make them an exciting fish to keep.

Boasting one of the more beautiful colorations, these fish are iridescent green with pink highlights underneath.Hi those fish are not that easy to sex. The males have a more streamlined body then females. Females are more compressed body, and thicker at the abdomen where the eggs are and higher in structure. Mature female cory cats are usually much larger than males.

They are egg scatterers. If you want them to spawn, put two males with one female and lower the aquarium temperature. Sometimes, they will also spawn in a community tank without any encouragement from the aquarist. Hello everyone, I am new to the aquatic world and have been reading a lot of the posts here.
