Information About Breeding Albino Corydoras Catfish

The Albino Cory Catfish or any Cory for that matter is not one fish that appears to be commonly bred by most aquarists. I have mentioned to several pet stores that I have successfully bred these species, few actually believed me!

I have kept Albino Cory Cats on 2 seperate occasions, and both times they bred quite readily. I have found them to be a relatively easy species to breed, and they will actually spawn in the community tank.

I will tell you about the most recent breedings, and some things I have learned while breeding these fish. Lets talk a little about the fish themselves. The Albino Cory Catfish (Corydoras aeneus) is a rather hearty species, and are easy to keep. Many owners keep them to take care of uneaten food from the bottom of the aquarium. They are a small fish, typically about 2 to 2 1/2 inches in length. They are bottom feeders, and they have short whiskers that help them locate food. They will adapt to a varied water chemistry and temperature.

These fish can be sexed easily. The females are larger then the males and are a bit "wider".

If the fish are well fed, they will breed right in your community tank. When they breed, they will deposit eggs right on the aquarium walls. Time of day doesnt seem to matter with these guys, although normally they are somewhat nocturnal, but not totally. It almost seems these fish never sleep. They will breed either during daylight or at night.

Eggs that are laid in a community tank will almost certainly be eaten, and if they arent, the newly hatched fry will be. Therefore if your Cory's are laying eggs, it would be a good time to move them to a breeding tank soon after they are finished. Some aquarists have been able to move the eggs from the community tank over to a breeding tank by peeling them off the glass with a straight edge razor blade. I personally have not been successful in doing this, but its worth a try to try to save some eggs from this breeding. A better approach if you wish to intentionally breed these fish is to move the fish to a breeding tank set up specifically for the purpose. They will breed again in about 2 weeks after the first breeding.

When I bred these fish, I used a bare 10 gallon aquarium with no gravel. I kept the tank about 3/4 full. I kept a power filter attached until the eggs started hatching, and replaced it with a sponge filter. I put the adult fish , in my case, 2 males and 1 female in the breeding tank. After a day or so, they started eating readily. I fed them well, keeping some food on the bottom of the tank. I just fed them flake food, in this case, TetraMin. The well fed female packed on the weight quickly and was soon ready to breed. They will breed several times doring a couple hours time. If this is the first or second breeding, about 100 or so eggs will be laid. She will release the eggs into her cupped pelvic fins with the males swimming frantically about her. in a short time, she will stop and will "rest" on the bottom of the aquarium for a couple minutes, then proceed to "paste" them to the sides or bottom of the tank. This will occur a number of times until they are finished. When the spawn is complete, the fish need to be placed back in the community tank.

Now is a good time to "vacuum" up any remaining fish food and debris from the bottom of the tank, being careful not to disturb any eggs that may have been laid on the bottom of the tank.

The eggs need very little care, however they will need to be in an environment where the water is circulating well. This is why I left the power filter in the tank to keep the water circulating. An alternative would be to place a decent sized airstone in the tank. If the water is not constantly circulating, a mold or fungus will attack the eggs. This is what happened to me on my first attempt. Out of the 100 - 150 eggs, I only had about a dozen actually hatch. The rest were damaged from the mold, which, for lack of a better term, looked like little "white fuzzballs". Healthy eggs are white, smooth, and are easily visible. For egglayers of the fish's small size, the eggs are rather large in comparison to other egglaying fish.

The eggs will hatch in 3 days. When they hatch, they will break loose from the egg and sink to the bottom. Now is when you want to replace the power filter with the sponge filter, and remove the airstone. One trick I did, was put the cylindrical sponge that I used over the intake of the power filter. That will work also.

The fry will live off of the contents of the yolk sack for a couple days, and within a week they will start eating fry food. When they are first born, you will see them "hopping" almost uncontrollably on the bottom of the tank. They will soon be able to control their movements better and will scour the bottom for food.

I have read online that the babies do best on live food, but being a newcomer to all this, and not knowing how or where to get live baby bloodworms or not wanting the hassle of hatching live brine shrimp, I opted to try a product made by "Hikari", called "First Bites". The fry seem to gobble it right up. This food is basically dry fish food in a very VERY fine powdered form. A small pinch between your fingers is enough. Because this food is so tiny, it will stay suspended in the water for a long time if there are strong currents flowing in the tank, this is why I removed the airstone. The sponge filter will restrict the flow of water from the power filter to the point where it will not create a strong current.

Feed the fry a small amount each feeding. Keep some on the bottom of the tank, not a lot, but these fish eat constantly when theyre young. You may have to feed 2 - 3 times a day. Feed when you see they have about run out of the "dust" on the bottom. They will grow rather quickly, and after about a month's time, they will be large enough to be placed in the community tank. I was able to place them in my community tank when they were about 5/8 inches long. Although that is a small size, the other fish didnt seem to bother them. I have angelfish, gouramis and the like in my tank, and they left the little ones alone.

If you plan to sell them to a pet store, you will want to keep them till theyre about an inch long, I would imagine. That is about the time when I plan on distributing my fish.

The videos on the right sidebar show my actual fish spawning, and the babies after theyre a couple weeks old.

I hope this narritive helps you in successfully breeding these fish. They really are easy to breed, and are a lot of fun to watch them grow.

Thank you for the information. I had some corys lay eggs. I didn't know what to do and may lose the first batch but I have a good idea how to make it work the next time.

I took a two liter soda bottle, split it from spout to the bottom, stapled to the two halves together to make an 18 inxh tunnel. Then put big holes all thru it for water circulation and trapped eggs inside of it that were on side of tank. I have hatched close to a hundred Cory's doing this.

I need some help. Yesterday I noticed about 20 little eggs on a piece of bamboo leaf inside my aquarium. I took them out about 8-10 hours after noticing them and I put into a 5 gallon tank with filter. The problem is I have 3 green cory, 3 albino cory, 2 peppered cory and 2 mystery snails in my aquarium and don't know whos eggs they are. Ive gone online to do research and the look like cory eggs they are just very small. I want to start breeding cories I just need a little help on my first go at it. Any advice or help would really help me out. If its not too much could you please shoot me an email at shipp17@ymail.com . Thanks again, folks. I realy appriecate it. Thanks agin!

I noticed my Albino Cory layi g eggs in my community tank..which has a gravel substrate & stocked with live plants..I came across your post & decided to follow your advise..I took all adults out, moved the air stone colser to one of the egg batches (there were many)..after 2 dats they started groeing hairy fungus..all looked dead..I decided to leave them till day 5...then I stated ckeaning bc they all looked bad. I siphoned the gravel..scrapoed the dead eggs..etc..siphoned out 1/2 tge tank and cleaned up the glass etc..To my surprise when I went back to add water I noticed several fry in the gravel..I took thr pump out immediately and wrapped it with sponge..but there was also a lot of fry in the pump itself...it's been day 11 and I have abt 30 fry growing like weeds..I just wanted to say thanks for the tips..it really helped me and now I have a tank full of baby Corys..����

"Your Freshwater & Saltwater Community Aquarium"
About 3 weeks ago, I successfully bred Albino Corydora Catfish.
I ended up with about a dozen babies.
The above video shows these little guys at about 2-3 weeks old.

I hope you enjoy the video!
Above is a video I created during a spawn cycle of 3 Albino Cory Catfish.
This was taken live in real time.
This process occurs a number of times until they finish.

★ Fresh Water Fish Facts ★

The Arapaima is considered by many to be the largest strictly freshwater fish in the world! The Arapaima, also known as Pirarucu, are beautiful, but they are a fish that can get up to 15 feet long and weigh as much as 440 pounds. They are fast growers, powerful swimmers, and in the wild will jump out of the water to snatch small birds from low hanging tree branches. Because of its large size this is probably not really a good choice for a home pet, but is well suited for a public aquarium
For more information on the Arapaima click below.
