I never had neon gobies jump. They like to live inside small conch shells and they spawn in there.

Gary Sorry bout your tang. Powder blues generally hate cleaner shrimp. Generally they do not make good candidates for cleaning and may even try to kill the cleaner shrimp. Of course someone will have one that thinks he is some other kind of fish and has learned to be cleaned, but, generally that will be the exception. Also, powder blues do not acclimate well to captivity. The losses can be high. It helps to hve a very large tank and lots of macro to feed them. And yes, I believe there is a false cleaner shrimp. Fortunately we don't see them for sale. Cleaner shrimp are one of the most sensitive to changes in water chemistry during acclimation. They are easy to kill, difficult to get ones from suppliers that are not already messed up to the point that they will die no matter how good you are with the acclimation process. My experience with them lately has been about 1 in 6 will make it. I guess that is better than wild caught fish do. Should probably be getting them from Tim. Perhaps he can get healthy ones that are not all messed up from the get go. It may take a month to come to realize they are not ok.
