I have a 5 gallon fry tank letting some grow out enough to start selling them that I had about 30 bumblebee, 40 electric blue fryeri and 16 demasoni from 3 of my females that had some at around the same time. I also have 2 snails, 1 Chinese algae eater, 1 red tail sand loach and 2 angelfish about 2 inches size. other than the demasoni fighting each other and the bumblebees fighting over territory a bit at first it has been peaceful. however all the demasoni went missing over a few days then all the electric blue fryeri went missing over another few days leaving only the bumblebee fry. any clue's what is going on? I am not seeing any dead fish in the tank other than a few on the 1st couple of days as there was a few injured fry that I had expected not to make it anyway.
