I've just got my betta last sunday, and kept him in a 1.5gal tank until a few days ago, where I moved him into a 5.5 gallon tank. I am new to bettas altogether, so I know somewhere I should have done something differently.
Anyways, I have gave him a little bit of food, but he never seems to eat it. It is just floating around. I'm going to do a 100% change tommorow to clean the tank. He seems fine, bjt he just doesn't eat.
Also I think from the stress of moving him twice in a week has caused his fins to start to rot. They were nice and blue when I got him, and the top fin stayed up. Now his fins just droop down, and are starting to get red tips. There is one fin that looks like it is split. I know this isn't good, so how do I help him?
I've tried a mirror to get him to flair his fins, but he doesn't.
