shell dweller tankmates

[fishstixs05]

I recently set up a thirty-five gallon hexagon tank with neolamprologus multifasciatus (shell dwellers) and a (sunset?) tropheus. the tank its quite high, and all in it right now is snad, lots of shells, and couple of large river rocks.
any ideas on decoration setup (rocks, etc) or tankmates would be appreciated.
Thanks
Ben

Would you want to keep fish that are only from the same waters?
Are they lake Tan. or Mulawi (I can't remember)
If thats the case I can't think of anything to go with them..

If not.. maybe a small pleco..

and rocks and shells..
you wouldnt be held back by the alkalinty problems with rock, so long as they dont have obvious metal content the fish do well with high KH/PH..
