I have had a betta in a cat shaped fish bowl for about 6 months and I was considering moving him to my 2.5 minibow aquarium but that tank has had a betta in their that either stressed him out to bite his fins or he tore them on something. So my question is their a chance this betta can get stressed and bite his fins that has nothing wrong with them or could he scratch it on something? If their is a chance that will happen I won't do it but if it isn't let me know.
