| Janitorial Crab Opinions
It seems there are varying opinions on whether or not crabs should be a part of a janitorial crew. What is your opinion? Please indicate:
* Size of your system
* Number of crabs (not hitchhikers - crabs you have added for janitorial reasons)
* Types of crabs
* Do you offer empty shells for hermits?
* Would you recommend them as part of a clean-up crew?
