Thanks for the links. I'll definatly check them out. I've heard that small tanks are harder to maintain than larger ones. If I were to get a tank, the largest I think we could manage to fit in our apartment would be a 30-40g, so not much to work with there.

Mostly I want to see something start off simple and grow to be very beautiful. There is a salt water store right down the road from me so I'll be checking them out. I've been in there once, but only to look. I saw rocks with very small little corals on them. Do those grow up to be the colorful ones I see in the large tanks?
