[Delphinus]

I might get jumped on for saying this, but I would guess no. A scopas tang or a yellow tang might do OK especially if you have "move up" plans for a bigger tank. That said, be wary about the bug because the fish can sometimes outgrow your ability to pay for a larger setup. That seems to be my problem anyhow but maybe it's not as bad for others.

A dwarf angel would also be OK in my view espescially if you have interesting rockwork. I picked up a potter's angel earlier this year from a fellow Canreefer who moved to the U.S. and I have to say I am constantly amazed by this fish by how smart she is. She definitely displays learned associations. If she and the tang "bump elbows" she will swat at the tang with her tail .... exactly how a tang would do it. She doesn't do that to any other fish. She also watches what the others are eating, then tries it herself. Thus, she eats the nori that's put in for the tang. She also scrapes algae off the glass ... exactly the same way the blenny does (if I let the algae film grow on the glass I'll have two sets of "kiss" marks). And of course she knows that the mandarin is the first fish to get fed mysis, so if I press the "feed" button on the wavemaker, she immediately seeks out where-ever the mandarin is sitting, and waits for the leftovers.
