Do you plan to upgrade tanks eventually? Good tank mates would be synodontis catfish, rainbow sharks, and (arguably) bristle nose plecos. They say the plecos lose eyes to the africans. I have 2 plecos in w mine, one has been there a little over a year and the africans ignore her. (I know, a year isnt that long in the broad spectrum.) However i do have a synodontis that lost an eye to an african. All these fish (including the africans) require a larger tank. A 40b or 55 would be in a minimum. Can you post pics of the 2 you arent sure about?
