Are Beta Fish happier in a little tank alone? or in a bigger tank with a few other fish other than another beta fish?
I have a 20 gallon with a few neons, tetras and algea eaters and then I have a 11/2 gallon tank just for my beta, but I feel feeling sad for him/her cause it's all alone in there.....
Can you tell if a beta is a female or male by their colors or anything?
