I don't know of any other fish that has such a "potato chip" syndrome as the betta . Your new guy is gorgeous Robin! Did you name him yet? I think I'm going to have to stay away from even looking at them for awhile. I went to the pet store last weekend and had a major inner battle when I saw an amazing black and white butterfly betta. It still makes my heart ache to think of it! But I just do not have the room and resources to add more to my plate right now. But, someday.... I will have more!
