Hi, some of my lace gourami seem to have split their pectoral fins (long thing "feeler" looking things). I have never noticed before (am sure i would have), and my mum pointed it out this afternoon. There are a few with a split/double fin on one side, and maybe one with split/double fins on both sides.
Do some grow more than one pectoral fin on one/each side (and somehow i managed not to notice), or is it likely that their fins have split? They don't look damaged, but the "double" fins seem slimmer than the single ones, so i think it is a case of the fin splitting. If so, what causes this? Should I be worried?
Anyone that could help shed some light would be much appreciated.
