Hey Otty, I dont have the same senerio(fish) but I do have a yellow and a kole tang. What I did was float the bag and acclimate it, of course. I let the kole tang out of the bag at night when the lights where off. The next morning the yellow tang was like nothing new was introduced. It worked for me. Hope this helped, Luna _________ 9YR OLD 90G/55g custom sump/refug Mag18 Aquac 180skimmer 692w MH AC jr,yel&kole tang,midas&convict blenny,B&G chromies,Blk/yel fin chromie blackcap,nemo,neon goby,6line; Blastomussa Merleti,Acan ,BUBBLE,Torch,LTA, Acropora(2) Moon, assort zoas, yel& G star polyps, P&B ricordia, montiporas, cup&candy corals, xenias,B/G mush,flower ane(2), cherry red mussa, dusters,cleaning crew..  |
