I've got between 4 and 6 platy fry living with 4 adult platies in a four gallon. They're about a week old, but don't seem to be growing (the fry are all 0.5 cm). I've been feeding them fry food but haven't actually seen them eat (they probably find food in the gravel though). The adults leave them alone completely, so the fry just swim carelessly around the aquarium.
Should they be growing significantly in a week? Am I just obsessive?
