I recently switched from a marine to fresh water aquarium. I've got a 200 gallon with 6 small africans. I'm used to different creatures with the marine aquarium. What else can I get to put in the tank??
some synodontis catfish will work. you might be able to try a lake malawi eel. with africans you have to find fish with the same water requirments (high ph hard water) that are also aggressive enough to stand up to the bullies of the bunch.
