I have some adult guppies in my 10 gallon tank and have been selective breeding them. I don't have much space so I just keep a few fry from each batch. Thing is, I have probably 60 fry (some a week old, some not a day old yet) I left in the tank because I didn't want them and they are swimming around like they have nothing to be afraid of. Which is true, because the adults ignore them completeley. Is this normal? Aren't they supposed to be eaten?
