Coming back to one of your original questions anabolism
I can't say that I have seen a bio-orb tank. I think that 1 goldifsh should be OK for a while if still small (but will definitely need a bigger tank later on). Although not shoaling fish, they are very social and do prefer the company of others of their own species. It is possible that when bigger, the goldfish (if it is one of the faster swimming goldfish) may try to eat the white clouds, but I'm not sure. White clouds are very prolific breeders, so you may end up with more than you bargained for.
