Hello! We got a brand new tank, and we know nothing about fish! Our neighbor gave us some baby platys. They don’t really seem to be eating though? We lost one already and probably another. They did move tanks 2x in 48 hours, so i am very aware that they were probably in shock. We bought the flakes that the store said they use to feed their platys, but they just seem to float to the bottom and not get eaten. Could they still be in shock? Or did i get the wrong food?
