fish for a tall tank

[BlueAbyss]

I agree with what has been said previously about the firefish, mine spends more time swimming in the open near the bottom in my 10 gallon and darting into his rubble pile. I don't think he would be a good choice. I do have a Hector's Goby that would be a good choice, if your tank can provide enough algae for them... he swims everywhere, picks at all rocks, and sifts sand. Really personable, non-aggressive.

now that you guys can see my tank, any ideas for corals? inverts? already got a green striped mushroom on the left hand side about halfway up the wall. I don't have immense lighting, so anything that needs that is out. thoughts on a brain coral? or a fan? pros/cons?
