Well, I am kicking myself in the behind. I woke up and my starfish looked like it had been slashed. Emerald crab I thought. The crab is also a prime suspect of the death of my yellow jawfish I had less the 20 hrs and my husband's feather duster. Not sure though and any advice on that will be greatly appreciated. After reading about starfish among all the threads I think it could be an acclimation issue. It seems to fit the descriptions. So what do I do now? Just let it melt away? Should I take it out before it is all over my tank? And what about the emerald crab, should I remove him and take him back to the LFS? Any advice would be great. Thanks!
