I recently got a 3" bowfin I have been growing out for a few weeks. Today I noticed some strands coming from his left pectoral fin. Can anyone ID what this might be? Thanks.
Seeing as how small he is the only way I can get a better photo would be to pull him out of the water and try to stop him from flopping which sounds like a disaster waiting to happen. Anyone else have any ideas? There defiantly not clear and pronged at the ends like photos I've see of Anchor worms.
