I'm new to Betta keeping and really need some help. Here's whats going on: I recently got a veil tail Betta named Aqua. Right when I put him in his bowl he got very lethargic (and still is).
Then out of now where his color became soooo dull and his fins started to rip. They are stringy at the tips and he is starting to look like a CT Betta. At first I treated him with Melafix until I heard it was bad so I stopped. Now I don't kow what in the world to do. Some other information is: 1 gallon bowl, not heated/filtered, no tank mates, no changes exept for worser fin rot and I have not testes the water yet.
