Fish4life Posted February 16 Report Share Posted February 16 This is my bristle nose pleco fish, Fanta, I got him a bit more then two months ago and when i got him his fin was a bit black at the top and a month ago i thought it was finrot so i used fin rot treatment but it wasn't going away. I dont see much of a dificulty of him swimming but recently i saw he also have some black on one of his side fins. If any of you guys know what this is or if you guys know how to treat it please tell me 🙂 Quote Link to comment Share on other sites More sharing options...
Caryl Posted February 16 Report Share Posted February 16 Hard to tell from the photos but I suspect nothing is wrong with him. Their natural colouring is brown and, depending on genetics, it may be a result of him reverting, or partially so, to his natural colour - like goldfish change colour as they age. It may stay like that or the dark colour may spread. If there is no redness or extra raggedness to the fin I would say he's fine. Their pectorals can get a bit tatty anyway as they dart in and out of tight places. I am interested in the wide red patch on top. One of mine has that too and I figured it was a result of him ramming himself into a tight hole and scaping the top of his body but perhaps it is normal. It comes and goes on mine and doesn't seem to affect him health-wise anyway. Fish4life 1 Quote Link to comment Share on other sites More sharing options...
