Def yuri, Gem tangs are one of the hardiest tang out there. Is ur Achilles better??
It's dead.
My Achilles would, in contrast to all my other fish, eat Ocean Nutrition #2 pellets. It selects them from all other food I blend. Quite funny to see it beeing soo picky, but it's taking interest to the #1 also now. It's gaining weight, and after almost 2 weeks, it's has settled down quite nicly and seems to be in good shape.
