Copper Banded Butterfly fish surviving

[BlueTang<3]

Well after doing a bunch of reading i purchased one of these fish again. Last time i had one it lasted until about a month after i ran out of aptasia and then parrished. I thought it was no big deal once i ran out as he was eating frozen so well that was wrong. Ihave read that they need a fatty acid from aptasia or from certain zoas. So asking around all my friends that keep theres farm aiptasia to keep them going. I am going to be doing this and posting my results. How do you keep yours alive. Is my idea going to work or do i have a far fetched dream.
