Have a situation here... Naso with Unicorn tang

[my2rotties]

Thanks for all the advise. The Unicorn is in the 90g still, and I spend more time interacting with her then before and she seems to be doing better. Lee brought the Unicorn's old tank mate here to keep her company, but although she shows a feeding response, she is still not eating. She is very fat and healthy looking so I am not overly concerned just yet.

I do not want to risk my other fish and this is why I asked if it might or might not be an option. Thank you everyone for helping me decide.
