Butterfly fish and sharp rocks

[kittyuk]

Hello,
Pantodon Buchholzi!
Has anyone got these fish? Is it worth getting a couple for a community tank?
and
We have grotto rock in the tank, it looks like cinders! The rock is rather light and pitted, but I wonder if it's a bit sharp for the fishes.

yes i've seen these in my lfs, there a realy unusual fish, they are nice, it was the feeding that put me of getting one,
as i was told they only eat live foods, i no the rock you mean, have seen it
nice rock but very sharp and would think that the fishes could easealy
scratch them selfs on it,
