So a few weeks ago I finally finished cycling the 5 gallon I got and was more than happy to put my betta in it after waiting over a month.
The betta seemed pretty happy about it to. I swear he never stops moving now. always on the go and swimming. However this week I noticed his tail has gotten reallly torn up looking. I'm puzzled because before while he's had minor cases of finrot while he was in the one gallon, it was never this bad looking. I know the water in the five gallon is much better than the water in the one gallon too. He's eating normally, there are one or two minor tears in his fins I suspect are from a plastic plant I might remove soon but the back of his tail looks less like a tear and more like rot I think?
Are the nitrates too high maybe? I don't think he's tail biting. Since he's been in the new tank his top fin has actually spread out and gotten much better looking than it used to so I don't know why his tail looks worse.
tried my best to get a picture but he hates sitting still.
