Yellow eye tang won’t eat.

[naesco]

The yellow eye tang eats the film algae that you find on the inside walls of your tank.
If your tank is large enough and you keep one side unclean it should be fine.
You can also make a pile of those smooth two inch stones you see in lfs which will also collect the film algae. After a while he will discover that some of the food you are throwing in tastes good as well.
