Help!!!!

I have a bit of a problem. I have a pair of Convicts who have had their 2nd batch of babies. They are very small, I would bet they just hatched. I had previously assumed that all the babies from the first batch had been eaten, killed by other fish etc. This morning I noticed the babies falling through the undergravel filter. This was because they cleared the bottom of all gravel. Anyways, upon looking under the tank, to my complete surprise I found 3 1/4 inch baby convicts. I assume these are from my their previous batch. I guess they got sucked under and lived off of the stuff that got taken in by the undergravel filter. I will have to remove my JD, Oscar and pair of Convicts before I can pull the undergravel filter up. The only problem is that I still have the baby Convicts from the 2nd batch to deal with. This is where I need you guys to jump in. I was thinking I would set up a 10 gallon tank. Then I would suck all the 2nd batch babies out and place them in one of those green nets you use to catch fish, then stick them in the 10. After removing all the other fish I would also pull the undergravel filter out and put the 1st batch babies in the 10 gallon. They wouldn't be able to eat the 1st batch babies, they could live in a big green net until they got bigger. I know this is a farfetched plan, but does anyone think it will work? Or any other ideas?

Thanks

I think some are still eating from a very, very samll egg sack. These guys are very young though, miniscule. You don't think the other Convicts, from the 1st batch would eat them? I am feeding them baby brine shrimp, they are slightly bigger than adult brine shrimp.

I'm guessing by destroy you mean taking apart the entire tank. All I have to do is bag each fish. Then remove the babies from the rock where the Convicts were nesting. After that I can remove the UGF and save the Convicts.

There is quite a bit of crap under there, which is what likely saved them.

It has been exactly 24 hours since I removed the baby convicts from the first batch and the fry from the second. I have placed them all in a 10 gallon. The temerature is maintaining at 79 degress. I have yet to add a filter and will go purchase one tomorrow. Anyone have a recommendation? I believe they will be fine till I tomorrow, any thoughts on this?

Thanks a lot!
