Yeah, I am always drawn to bottom living fish for some reason. The angel was an impulse buy thanks to the lfs scaring me about scarcity after 3 major disasters. I figure once it's grown out a bit I can rehome it, especially given it's easy going attitude.Depending on the species, I believe it could work. You would have to get one of the smaller, more placid varieties. I would watch out for conflict between the acara and geos as both are medium sized cichlids that generally occupy the same levels of the tank.
