I purchased a yellow tang from someone who was closing his tank seemed healthy and swimming normally in his tank, I put it into my 10 gallon qt tank been 1 day without copper yet he is still small, but he’s in a corner not swimming seemed stressed not eating and looks like it’s breathing. Heavily, debating if I should take a chance and put him in my display tank with only a leopard wrasse, or wait it out a couple more days to see if he starts eating or calms down worried any suggestions
