55 gallon, Will this work?
 

Hi all, I have gotten the okay to get a another 55 gallon. It would go to my parents work place, because they thought that it could use it. My mom wants angels, I want a large colony of shelllies.I think If I show her some of the other fish besides the shells that would work in there she would be okay with them instead of the angels, heres the question: what other rift cichilids would go with the shellies, and they would have to be from tangynika, The exact shell dweller I want are the following two: Lamprologus Ocelattus and Neolamprologus Multifasciatus. I could also tank my nature style 38 gallon and get a 55 at my home, would rummy nose tetras take flake as well?
