I have a 29 gallon tank with 8 adults guppies. One female gave birth and at 1st was thinking of moving the fry to own tank but I'm not planning on breeding guppies for retail... although lol I might have to find homes if they have their way. Well I have about 18 fry swimming around like they own the tank and the adults seem to leave them alone. Is this normal? Is it because I am feeding them well and theres plenty hiding places for the fry?
