Baby C. Elegans In My Tank!

[Evad]

I am taking it that breeding Cories must be relatively easy and common? Because after having 12 C. Elegans in my tank for about a month, I now have babies swimming around. I did absolutely nothing to cater to this and in fact now I am concerned what to do with them all.

Anything I should be doing to keep them growing? Or since they hatched on their own the conditions are already proper for them to grow up...

Congratulations!

The answer to your question depends on a lot of things:

Are there other fish in the tank? (zebra danios, angel fish, etc.)

How big is the tank?

What is the substrate? (if any)

Do you have a spare 5 - 10 gallon tank?

For the first several days the fry will live on their egg sacks. After that they need some time food like daphnia. In a large community tank it's hard to get then the food they need. That's why it's usually better to move then to a smaller tank with a bare glass bottom. There you can get the daphnia, hikari first bites, boiled eggs yolk, etc. to them. It's also easier to keep the tank clean.

But if you're not particularly concerns about their maximum survival rate then you can feed the above items sparingly (don't want to foul the whole tank) and hope they get to eat some of it.

Good luck and cheers.

Thank you and very much. It appears I only have only 3-4 baby cories and according to the pictures I am seeing they appear to be 2+ weeks old. So they are already eating regular tablet foods. They sure are cute.

I don't have anyting in the tank that would eat baby fish at the moment. But I will have Angelfish soon.

I guess I was surprised to see C. Elegans spawn because I hadn't found any books tht said this was done before.

Thanks again!

Ok, I thought these were newly hatched.

As long as their bellies a big they're getting enough food. Be sure to feed them a variety of foods and not just tablets. Nutritious flakes are good and once or twice a week frozen brine shrimp and (when they're older) frozen blood worms. Even an algae wafer every once and a while is good, just don't let it sit there after an hour, clean it up. Of course, you don't want to over feed and please do a 20% water change once a week including a gravel vacuum.

elegans aren't that hard to breed. Some other species of corydoras can be a challenge though.

Once you get the angel fish, watch out; angels love fry of any kind.

Cheers.
