Hi I’ve over fed my babies and now they are fluffy and their gills have all gone , they had a film over their eyes ... OMG how scary ! I’ve since learnt a little about ammonia and nitrate . I’ve been bathing them in salt baths twice a day and I think we are through the worst of it my question is ... now that I’ve got the tank sorted and most of the fluff has gone when can I put them back together in the tank ?
