I'm not exactly sure what is wrong with my betta, or if there is anything in fact wrong with him. But I just want the advice of experts.
Some background: Nigel (my betta) lives alone in a heated/filtered five-gallon aquarium, the PH level is currently at 7.3 and the water was changed 2 days ago. I bought Nigel from a pet store about 3 months ago, I felt bad for him because he was in a tiny cup with disgusting water. He turned out to be a very pretty fish.
The little thing that is worrying me is the fact that he has some crust on his face. I don't know what it is or if it is just the way he is. He seems to be a very healthy fish, constantly swimming around and exploring, more than happy to eat a few betta pellets. I've tried using a product called " API general cure" which is supposed to be a medication for various parasites and diseases.
But it didn't really clear anything up.
I'm not sure what to make of this, can anyone offer an answer/advice?
Sorry about the crappy cell phone pic.
