Hey guys, I'm new to the forum but was hoping to get a bit of help. My husband and I purchased a whiptail catfish and several other fish to add to our 55gal dirt planted tank in the living room, but when I went to put the whiptail in the tank I noticed some spots on him. While he was in the net the spots seemed slimy and raised so I freaked and put him in my 20gal tank in the bedroom instead. The spots look fluffy and unlike anything I have encountered before. I'll attach pictures. Any insight would be great. I feel bad about putting my goldfish that live in the 20gal at risk, but there are many more fish in the 55gal then there are in the 20gal so it seemed the logical option. You know, poison the few to save the many?
