While I was doing some research about the sorts of fish I'd like to keep, I read somewhere that marbles were better than gravel. I think it was for some sort of dragon fish, because gravel can scratch them when they try to dig.
I don't have dragon fish (probly won't for a while, I'd need a whole new tank and equipment for it), but I do have guppies, molly and neon tetras.
Now I'm concerned that they might somehow end up getting trapped in the space between them. I figure I'd put at least an inch of them at the bottom, maybe that'll pack them down more. Does anybody know if this truly is better, in general, than gravel?
