My new fish arrived yesterday! Two of them are Senegals which are my first ever Polys.
Both are already eating (sliced earthworms). They're about two inches long.
Unfortunately one of them is missing a pectoral fin and overnight it's turned into a balloon. Some sort of infection? What do I need to do to treat it?
Sorry about the photos, they barely ever keep still and when they do it's out of sight.
