I'd be thinking about midwater catfish, such as Kryptopterus or Dianema. In small tanks, schooling midwater Corydoras would be fun, for example Corydoras hastatus.

Otherwise, some of the schooling mormyids (e.g., Pollimyrus isidori) might be appropriate, if water quality and aquarium conditions allow. In hard water areas, the blind cave tetra Astyanax mexicanus could be kept, though it is a fairly bullish animal that only works with equally robust tankmates. Similarly the South American puffer Colomesus asellus is a gregarious midwater fish that buzzes about all the time, but it is somewhat nippy, and can only be kept with specific types of tankmates, certainly nothing slow, stupid or long-finned.

thanks for the response, but a puffer is out of the question, the last thing i need is to have a puffer ( who i have a hard time blaming for anything) chewing on my bgk, i might look into some cats, i had a crazy idea last night im glade that passed. my lfs has a lung fish, and although there not mid swimmers per say i know them to be active enough to help my problem. but i don't think i want to deal with the monster it becomes.
