Typically, I have done very well with my corals with the exception of one. Back several weeks ago I purchased a frag of Blue Steel Zoas in which I acclimated and introduced to the tank. I run T-5's and the placement was on the bottom third of the tank. The first day they were very hesitant to open. The next, one started to implode so I thought it was still too much light. I lowered the zoa and none opened. I raised the next day to a higher light and they started dying eventually all going to zoa heaven. I now have an order placed for some bright blue zoas due in sometime next week. I want to get it right so anyone who can suggest placement for these guys I would appreciate. It seems the blues are the only ones that I can't figure out.
