So one of patients here got a platy fish as a gift. It was brought in what seems to be a cup. I know to start with that thing is too small for any kind of fish, I think even for fry. But I kept telling the mother that the fish would die if they didn't put all those things tanks need, and well the need of a bigger tank and the cycling. But she kept insisting that the fish didn't need such things. Can platys live like that?
