I had several screw ups:
1. Buying the cute little Sailfin Tang for my 90g tank. A year later I had to buy a
225g to house him.
2. A fist-sized piece of rock covered with mushrooms and/or palythoas for $10
each. Of course I bought both of them and have been trying to get rid of
them ever since.
3. Me: "Why is your RBTA brown?" LFS: "Oh, it is a Rose BTA. It just hasn't
coloured up yet."
