The RED List of Fish, Inverts, and Corals

[Treebeard]

I think these list ideas are good, but should only be used as a guide and not the fish keeping bible.

And for an entertaining afternoon, I think it would be fun to take the list around to the local fish sellers and see how many creatures from the list are for sale, and ask the staff if they are easy to keep. I bought a nudibranch from a lfs and ended up returning it when I found out it would slowly starve. Of course the guy at the lfs said they would eat algae from my tank.
