I brought Epsilon home less than a week ago. He was the scrawniest betta at the fish farm, but I thought he was beautiful so I took him home.
He is dark blue with a black face, but over the last few days his belly has turned white and his face has whitened considerably, and this morning I discovered some kind of sore on his face near his gills.
He keeps wedging himself into tight spaces, like behind the filter. Could this be a sign that his skin is irritated?
I keep him in a 3 gallon cycled tank with 2 small plants and a filter. I have done 1/3 water changes twice this week and gave him a salt bath this morning. He is eating well.
I'm not sure what's wrong with him. Whenever one of my boys gets sick, I usually lose them, and I don't want that to happen again here. Is there anything else I can do?
