Cyst on Female Betta Tail

215 Views 0 Replies 1 Participant Last post by  sabhan
Hi everyone- I’ve been researching like crazy and came across this forum. I haven’t been able to find anything similar to what’s going on with my betta so I decided I’d post and hope for any luck. About 3 weeks ago my female betta, koi koi, started growing a lump on her tail. I started doing more frequent water changes and monitoring it but it’s only gotten bigger.
About two weeks ago I put her in a quarantine tank and dosed her with bettafix for a week but it didn’t do anything. I did a 100% water change, let her rest for 3 days, and then tried berra revive. It’s been 4 days with no luck and she seems to be getting stressed so i moved her back into her original tank (she’s the only one in there so I don’t have to worry about anything spreading).
The lump has only gotten bigger and is turning black. I’m not sure if this is a tumor or a cyst or what. She’s lost a lot of her energy as well and is starting to swim as though her tail is weighing her down. I’ve been checking ammonia levels daily, and have been dosing the tank with seed bacteria as well. I was doing 25% water changes every day in her quarantine tank but I’m not sure what to do in her normal 10 gal one. I’m really worried at this point and have no clue what to do. Any help would be greatly appreciated!
