HELP please anyone? We have baby fish and not sure what to feed them on...?

this may sound stupid but our shibumpkin (sorry about spelling) was making loads of eggs. We put them in a seperate tank and after 6 days they'd just gone fungusy. So we took the plants out and washed the eggs off to put back in the big tank with all the fish. We went to empty the water and put the tank to one side and we noticed about 30 to 40 baby fish but they were sucking the side of the tank... Like our loaches do in the tank with the shibumpkin. I did rescue a few clumps off stringy stuff but we think in the end they were just poo. Question is is have we managed to cross breed a shibumpkin and loach? Just it seems strange our shibumpkin was making eggs and now this has happened. If so what do we feed them on? Or are they just baby loaches in which case how do we sort out a filter? The filter that we have to fit the tank would be too powerful but the new size down we have which we used to use just for the snails sucks stuff in. (the snails were big enough not to be sucked in) Thanks loads in advance.
