Min. tank size for harlequin tusk?

[kdlbem]

I just got a 65 corner tank, and I'm trying to come up with a fish or two to go in with a hawiian zebra moray. I'd like active fish that stay out in the open areas of the tank. I am thinking a potters angel, and one other fish(tuskfish). If the tusk won't work, any other ideas are appreciated.
Thanks,
B

I figured a tusk probably wouldn't work, but I didn't even stop to think about the water quality issue with the angel. <img src="graemlins//uhuh.gif" border="0" alt="[U-Huh]" /> Thanks.
I have thought about a dwarf lion, but that's two fish I would have to keep an eye on when cleaning <img src="graemlins//eek.gif" border="0" alt="[eek]" /> Is there a dwarf lion that looks similar to the volitan?
Thanks,
