Shelldwellers In A 20g?

[Genesis]

I know a member of this forum Fella has succesfully kept Neolamprologus multifasciatus in a 15 gallon.
I was wondering whether I too could keep multis in a 20 (us) gallon (tall) aquarium?


If so, I was thinking of making caves out of pebbles and rocks, would this be alright? or do I need actual shells?

Also, would they be okay with 5 male Poecilia wingei?

Multi's do pretty much require shells for breeding. The endler's wouldn't be any problem either way.

I'll be setting up pebble caves and I will ask at my LFS if I can have some of their dead apple snail's shells for the Shelldwellers
