Regular Member Captain Findus Goldfish Posted August 3, 2010 Regular Member Share Posted August 3, 2010 I noticed today, while doing a water changes, that Sir Lancelot has a sort of 'mole' on his tail. You cannot really see it unless you look at the tail from the top - it appears like a little growth, in the middle of the lower part of his 'left' tail. Otherwise, you don't notice it, it is black just like that part of the tail. So I was wondering, can they get mole-type things? Can the fins grow some 'bumps' of fatter skin? In a dog you could also say it was a 'tik'... Can fish get similar things? Must I do anything? Params, Ammonia 0 Nitrites 0 Nitrates 0 pH 8 tank size 40gallons, 3 fish, 10x filtration. Not cycled and not trying to cycle this tank (separate fishless cycle is in progress) - I do frequent water changes for now. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member Sakura Posted August 3, 2010 Regular Member Share Posted August 3, 2010 My ryukin Yoshi arrived with something just like that on his tail fin. I think it is damage from shipping in his case, but I'm not sure what it could be with your fish. Is there any chance he bumped into something sharp? 0 Quote Link to comment Share on other sites More sharing options...
Regular Member Captain Findus Goldfish Posted August 3, 2010 Author Regular Member Share Posted August 3, 2010 the tank is bare except an airstone unless he bumped it in the intake or something. should I be worried? it't not like an embedded parasite or something nuts? 0 Quote Link to comment Share on other sites More sharing options...
Admin koko Posted August 4, 2010 Admin Share Posted August 4, 2010 If it looks smooth like the fin its self i would say dont worry to much, keep an eye out. If it looks raised then I would say try to get a pic so we can figure it out 0 Quote Link to comment Share on other sites More sharing options...
Regular Member Marlis Posted August 4, 2010 Regular Member Share Posted August 4, 2010 What Koko says is right. Goldfish can get purely cosmetic growths, but I'd keep an eye on it. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member devilduck Posted August 4, 2010 Regular Member Share Posted August 4, 2010 Rusty has one on her tail, has done since I've had her and that's about 8-9 months now, it's never done anything other than grow with her tail, never out of proportion and it's never changed colour or fuzzed or anything nasty. It's slightly darker than her tail but still has been consistent 0 Quote Link to comment Share on other sites More sharing options...
Regular Member amynmitchell Posted August 4, 2010 Regular Member Share Posted August 4, 2010 Tinman had a few spots like that came and went. I worried, but then figured out it was just him. 0 Quote Link to comment Share on other sites More sharing options...
