The Life Cycle of The Cory Catfish

Updated on April 14, 2014

Cory Eggs

Early this morning I noticed a batch of cory eggs on the side of our 29 gallon aquarium.  Since we only have guppy and molly fry (both are livebearers) and 2 juvinile bristlenose pleco's in the tank, I knew it had to be the cory cats.

Although it is ideal to have at least 3 of each variety of cories, I currently have one spotted cory (the other 2 I got with it died), and a pepper cory, and what I believe to be 2 green cories.

I'm pretty sure the green cories are the parents, since most strains of cories don't school together, so I'm pretty sure that they won't spawn together either.

This lens is going to be a "baby book" if you wish for the cory cats.

Stick around and I'll let you know how they're doing, what I'm feeding them, and I might even have a few pictures for you as well.

If you look at the right side of the aquarium glass you'll see lots of little white dots...these are the cory eggs.  They're laid here, and on one other side of the aquarium.

So far we have counted 88 eggs!

We've also moved all of the mollies and guppies out of that tank, into our 55 gallon tank.

*Update*

Unfortunately, even though I had been assured that bristlenose plecos would not eat eggs, they did, so no cory fry for me.

Hopefully we will have some soon!

Cory Update - 9/07

Although we've seen a few more batches of eggs, we still haven't seen any fry.

The mollies and guppies love eating the eggs though, and it's funny to seem them swimming around with eggs stuck to their lips.

Poor things. I was worried about them at first, but the eggs eventually fell off, and all of the fish are fine.

We moved the cories to their own tank last night, so hopefully we'll get some more eggs, and see if they'll hatch this time.

I'll keep you updated.

Do you have cories, or Coryadoras Catfish?

My cories spawning

I noticed the cories were spawning this morning, and I managed to take a pretty bad video of it with my cell phone.

The female held the eggs in fins under her body, then wiggles over the amazon sword plant leaf. When she was finished there were 7 eggs on the leaf.

Do you have cories, and have they ever spawned?

      [in reply to N. alex B.] The females also tend to have bigger bellies when they are adults. If you buy a group of cories, which is the preferred way of keeping them since they are a schooling fish, you'll more than likely get a male and a female, but you don't always see the eggs even if they do breed.

      I've heard of breeders who wake up in the middle of the night to collect the eggs before the cories keep them.

      Im not surprised ur eggs survived the power short, tropical fish r adaptable to differing temperatures,(though they prefer warmer temperatures!)

      as i said in my comment (up^), unless u wanna go to lots of trouble, the only way to tell gender is to see who is bigger at adult size. Since both o' mine are juveniles, i can't tell if they r different genders and if they will breed! (i hope they're different genders so they'll breed and ill get babies!)

      Hi Rachel, congrats on your cory fry!

      It must be so exciting, especially since you were dealing with a power outage.

      My cory cats just laid eggs last Thursday. I took out all eggs and put them in an empty 5 gallon tank with pond snails. The pond snails, I read, only eat the unfertilized eggs. I left the filter off, put the eggs in java moss, treated the tank with pimafix (keep fungus off eggs), and left the light off (keeps fungus off). Sure enough, 5 days later, the eggs have hatched. They are now 3 days old and there are probably 100 of them. Ive turned the filter on with netting over it and am going to buy them some food tomorrow. I had some daphne (spelling?) but it spoiled due to power outage. Im so excited, I didn't expect them to hatch or have so many! Or even live through our 4 day power outage!

      Ooops make that they were in their own tank for 3 months, not 6 months. It seems like a lot longer than that though :-)

      Hi Penny, we just had a batch of cory eggs in a community tank, but I don't think any of them made it. We didn't have anywhere to pull the other fish out.

      We had the cories in their own tank for about 6 months, and we never saw any eggs, I guess they just must have liked this tank better.

      You can read about our most current experience at Bronze Cory Spawn.

      I'd love to hear about your experience with cories if you try.

      We've got a pair of angelfish laying eggs, but so far they are fungusing.

      Wow, I'd love to see all of your cory kittens! They sound so cute.

      So far all of our cory eggs get eaten before they hatch, unfortunately.

      I have 2 male peppered,1 female peppered,and 1 male albino cories and they mated producing 20 eggs. I moved the eggs to a 1.6g aquarium.About 5 days later I had cory kittens! They are now 14 days old and counting.(I bought 2 green cories 4 days ago and they are fitting in good w/ other adults)

      Wow, all those fry sound like fun.

      Are you having trouble with other fish eating the eggs, or are you moving the eggs to another aquarium to hatch?

      I brought a female albino cory that was full of eggs to go with my 2 other albinos hoping they would spawn and now I have over 50 albino fry they are about 5 days old and they are doing well I have them in a small tank with a airstone and feed them liquid food at the moment.they are so cute

      i have 2 albino cory cats and had one bronze cory. they breed like crazy. all the fry are bronze, so i have to guess the bonze mated with the albino. i now have about 13 corys in my 55 gal tank. i love to watch them. i am so excited every time i can spot one of the small fry to watch them grow.
