Kevin, I've herd from most of the people that I know got acros from me at and just prior to the swap, and most did ok. sorry to hear yours did not make it. Btas can and will split from stress that particular nem was a clone that had not split for over 2 years and was ready to do so soon. I'd feed them 1-2 times a week with, good quality raw table shrimp from the grocery store as well as pices of silversides of other ocean fish. Starting as soon as they will accept food. From experience they are more likely to take to the shrimp first. In my tank the nems stay near the bottom in the rockwork (rember though I have 400w 10K xm lighting in a 70 gallon tank(verry high light)they may need to be closer to your lights then they were in my tank. If they are not happy lighting or watermovent wise they can and will wonder arount your tank. If and when they wonder they will sting and harm/kill corals as they contact them so be carefull with your selected placement. also cover all pumps intakes well, this is possibly the #1 nem killer. these are manny generations captive bred btas and are as hardy as nems get. When I added them to my tank I was lucky and they liked their placement. The only wondering I've had is after spliting.
Good luck with your btas. I am asuming your soft coral frags made it? and you only lost the sps.
As for my tank most of the fish, snails, leathers,btas and zoas are still with me. All shrimp,serpent star, britlestars, urchen, crabs, sps, lps, and xinia are completly lost. My water quality is still shaky but geting better. I think the death and destruction are done with.(knock on wood)
Steve,
