I have a betta that has the signs of what i concluded is fin rot (loosing color, tattered fins and also has little white specks on tail also which i belive is ich) i have been cleaning the tank every week since i have recieved him. I have have been treating with tetracycline hydrochloride for 4 days now. today ends of fins are black and seem to be getting shorter. Is "captain" getting better or worse, if anyone can help i would greatly appreciate it! I love my fish and don't know what else to do!
