Cleaning crew dying

[goodgreef]

Hi reef types,

Just found a little green crab that was dying. How long should they live? Should I be feeding them anything special? It seems that snails and crabs have a very short life span. I hope i'm not killing them by doing something wrong.


Tanks

invertebrates are sensitive to water parameter changes.... what does your water test at for salinity, ph, alkalinity, etc.?

what size tank and what is the cleaning crew and how many of each and how long has your tank been running?

Temperature swings will wipe them out quickly too.
