i dont know how sure i am about the river rocks.. i mean they will look a bit more natural, but the decorations we have do look nice on the blue.. heh i might change it all then end changing it all back again... i've no clue.. heh.. i think the smooth rocks will be better in the long run tho..

You could always do the natural-looking gravel, too . Just another idea. That's what I use...except with my frogs because they might eat it.

The only issue is how would you clean the stones? I just thought of that now. I use them in a smaller tank that gets 100% water changes but in a larger, cycled tank I don't know how one would go about cleaning them. After all, a gravel vac wouldn't pick them up =/. You know what I mean?

hmm.. i never thought of that.. most of them are pretty small.. but they might be heavier than gravel.. heh woulda never thought of that.. might have to do a little of the tank and try it?

Yeah, I just don't know if the vac would pick them up. But hey, give it a shot and tell us how it goes .
