Okay! Thanks a lot! I just wanted to be sure since I've never dealt with it before.lilirose said:Fin rot usually starts with brownish patches that become black. It's also almost always caused by poor water conditions, and the best cure is to increase the frequency of water changes.
I don't see fin rot here. His fins look pretty healthy. However, it's very good to pay attention to subtle changes in the condition of your fish, and start fixing a problem as soon as it appears. That said, some Bettas do change colour- sometimes drastically- throughout their life.
