I purchased a half moon betta from Petsmart back in October. In November i noticed a slit in his tail. In a few days his fins appeared to be falling off rapidly. So far his tail was the only fin affected but a few days ago I noticed his lower fin beginning to deteriorate.
He is housed alone in a 10 gallon aquarium with a filter, heater (set to 79 degrees). There are live plants but no decorations (I took them out as I did not want to risk any more tears).
I have treated him with Maracyn 2 - which had no effect. I then started using jungle fungus tabs. I went through one treatment and then began to see fin regrowth. However, about a week later i noticed that his fins were getting worse again. I did another treatment of jungle fungus - and this time I noticed he was getting worse during the treatment. I have been doing water changes throughout.
I am not sure what else I can do...He is getting worse by the day. DOes anyone have any suggestions?
