I have a 4 foot tank which I have been putting young Hypans in for the last couple of years, I recently put some powdered food in and these fry appeared from everywhere, there looks like about 3 generations in there but | am not sure what they are? There are L002. L052, L340, L066 and a couple more in there but I am leaning towards L002 with these - anyone hazard a guess? I should have separated all the adults ages ago to avoid crossbreeding but these all look the same. I saw a couple a couple of months ago but had no idea there were this many in there.
