10g reef w/10g sump

This si cruel, and stupid. You're idiotic for keeping that fish in that tank this long. Take a hike.

don't let the cruel remark above discourage you, some people on these forums are very picky about tank sizes and tangs. We call them the Tang Police, they are feared across the land and when they come they are not very nice. The person above obviously does not realilize that you said you'll give her up soon, and that it has been alive for about a year.
