Ensure highest water quality and a varied diet, rich in nutritious marine-base vegetables to keep your Blue Tang in optimal health.
Diet, I had a baby 1 inch scopas in my Evo for about 6 weeks or so to fatten it up before going into my big tank, as stated baby tangs want to graze all day and there are 4 types of macro in my Evo as well as micro algae, unless you get really grubby rock I would move it on.
