Hello, I have a biorb of 4 3 platys and 3 black tipped neons and yesterday I suddenly noticed that there are 7 platy frys swimming around the bottom of the tank! very unexpected as we've had the fish for about 4 months and I just figured that the boy didn't fancy the two girls lol At present they are doing okay and I am scrunching up the flakes as small as possible so they get them too, they are about 5mm long, anyone have any ideas how long they take to get bigger? worried that the other fish will eat them
