my full grown guppies in that tank are fine and never disturbed, but do i have to wait until the fry are all adults before letting them loose? i have 9-10 fry i am keeping in my net in the tank and they are just developing their side fins and their back fin is growing slightly in size. i feed them crushed up cichlid flakes since i don't have any liquid fry food. they seem to be doing fine, but i know that if i keep them in the net for too long they will start to get stressed. how big do you think i should let them get before releasing them into my tank?
