Barrier Reef has a ton of tiny Blue Hippos, I see them there nearly every time we go. $28 if I remember right.
We had two, one lasted a week. One lasted a couple months until a parasite got him. All other fish are fine. No more blue hippos for me. lol
I personally don't care about the tang, I just remember them flipping out on me last year. I am also told all the tim that my 1.5" coral beauty is way confined for my 29g. I never heard him complain once.
