I thought ti might be something you'd do, but figured I'd mention it just in case.
I didn't know that, but I don't know anything about goldfish. I guess they're bottom-feeders...? Prob going over all the gravel getting any tidbits that collect. Marbles sound likea good alternative. You can always get a clown-loach to get in between them to keep them cleaned - the loaches are more "delicate" eaters and don't really turn stuff over. They're also active, and funny to watch.
Right now, Ihave 5 "glow light tetras", and they're boring -they hide most of the time and only appear when I put food in, and they finally figure out that, oh, duh, yeah, this is food. IOW they're kind of dimwitted IMO even for fish.
I think my tank might be too small even for goldfish...
