Just found a baby (cory?) in my tank - what do I do with him now?
I was cleaning my big tank today and getting ready to dump the bucket when I saw something wriggling in the bottom. I quick stuck him in a square vase I had laying around with some clean water, moss and a few tiny bits of other plants, but I honestly don't know what else to do to keep him alive! I know the moss must have some infusoria on it. Should I add more of that?

Not a great pic, but based on how much my cories have been breeding lately and his shape, I'm guessing that's what he is. baby cory by KPainter, on Flickr

Here's his makeshift tank - I stuck a piece of white paper behind it so you could see it easier in front of my other two tanks. It's tiny. But so is he. And there's no one in there to eat him.

Any help/suggestions you can give me to keep this guy alive would be great! I have an air stone, but in a space that small, it would probably blow him away. Water changes every day? Any thing I can do for him food wise? Help me, y'all!

Neat! I'd suggest getting some frozen baby brine shrimp (BBS) to feed. Keep up with water changes, the shrimp will foul the water quickly. Don't overfeed - it takes much less food than you think for one lone fry. You can also grind up some flake food very fine and put a very, very, tiny pinch in.

One option to improve water quality is using a breeding "net" /chamber that you just hang in your main tank. Much easier than doing daily water changes. Should only be a few dollars. Something like below:

I thought about doing the breeding net. Maybe that's what I'll do. Then he can go back in the big tank. I'll look into the frozen brine shrimp!

I will float a plastic container in the tank to keep the water temp the same and just draw water out of the container and replace it with tank water. Add some plants and use a turkey baster to suck detritus off the bottom of the container.... works if no breeding net available. I've been doing this for some small shrimp growing out before I put them in the tank with the sushi lovers. The net would be easier as no water changing is needed though.

I just bought a hang on the side breeding tank and some brine shrimp eggs - both should get here Saturday, so if I can keep him alive until then maybe he'll make it.

I also just crushed some flake food to dust and put a tiny amount in. I'll change his water tomorrow. He doesn't seem to move much except for some bursts of craziness...then nothing again. I hope he's all right.

The net was a good plan.

As for food, the easiest is to place some plants from the main tank inside the net. Infusoria will abound, and corys will eat them. But given his size, I would go immediately to sinking foods. Shrimp pellets, disks, tabs etc. They will sit on the bottom of the net. Of course, fish below will pick at them.:-)

I found a cory fry in my canister much like this one time. I put him in my 10g which at that time had nothing else in it but some Farlowella fry, and he grew quite fast even though I wasn't feeding him except for some sinking foods.

He's still alive and kicking today so I'm happy! I put a bunch of moss in there, which he seems to like to hang out in. On your advice Byron, I dropped a sinking pellet in there too. He's ignoring it so far. Also changed about 50% of his water today.

KPainter 06-08-2013 08:56 AM

Still alive as of this morning, although he must not like waking up because he was a little slow to get moving at first. Then he flitted all over the place, so I'm sure he's fine. Changed half his water, siphoned out the particles I could see (I'm using my finger over the end of a drinking straw for that) and added a little bit of crushed sinking pellet for his breakfast. The breeding tank comes today and I think getting him in that will make me feel better about his survival chances.

My cories were spawning again today and I managed to get four eggs out (they don't lay a lot) and into the little tank with the hatchling. All the eggs were in the moss, so I'm thinking a spawning mop might really work if I ever decide to really make a go of breeding these guys. No idea how the eggs will do, but at least my breeding tank arrives today.

Well, this sucks - the breeding box just came and as I was setting it up, I realized it was cracked on the bottom corner and won't hold water. SO disapointed! I hope they send the replacement quickly.
