I've recently shut down my 20gal and moved my betta into my 50 gal. However with the flow of the filter he usually floats to the top. I think if he went down to the plants he would be okay but since my plants are only half the height of the tank he is usually just floating at the top. He has been in there for a couple weeks now. Should I be concerned and try to make a new home for him. Anyone else have them in community tanks what is their behavior like?
