I would like some ideas concerning fish for a new heavily planted twenty gallon high with a pH of 7.2. There are currently two Otos, and I was thinking about six of one type as well as maybe a Betta or some other fish that could be a focal point.
Consider rasboras. I have 8 of them in my 20 high along with two otos. I think they are beautiful, mine are quite active and very interesting to watch.
