Be patient with the feeding, mine took over a year to eat anything other then nori. I also took care of Achilles in a surge zone exhibit in Baltimore, many times some of our new arrivals would be stuck on only eating one thing for the longest time. Most important part is they're eating something ;-)
Thanks, that's good advice! It's funny, my AT goes bonkers for spirulina brine, samples nori, occasionally tries mega marine, but completely ignores anything else. You are right, though, at least it is eating something! I think I will keep it in my intro tank for a while so it can slowly fatten up.
