:cry1: I have a 220AGA with 8 chromis and a friendly YT, i was worried but i added a smaller blue tang to the tank, everything went great and the two tangs love eachother, they always rubbin eachother and kissin. Well my YT is the biggest fish and the boss of the tank, but she is also a scardy cat for the most part, never thought i would have problems with her. So i went to the LFS and bought 3 Bangaii Cardinals and added them to my tank, the first day two hid and one was kind of out in the open, seemed to acclimated nicely, well the next day the two littler ones were still hiding in the back and the big one was gettin pushed around by the YT and it kept hiding under the rocks, well that was three days ago and i havent seen the cardinals since, im writing them off as a lose, but what should i do differantly........ (rearranging my rockwork is kind of out of the question)
