I'm a little worried that doing anything like that would cause other stuff on the rock (like corals/algae) to die. Other than the one pink crab I haven't seen anything bad ... but ... anyway I'll probably keep watching for a while.
, Roger, yes I do intend to put all this stuff in the garbage disposal. If enough creatures come out then I'll get the grinding out of my system. Won't have to sacrifice any kittens/puppys to the disposal gods this week. [i.e. wanted dead or alive ... Roger's sense of humor]
In reality if I find bad stuff it will most likely die before I find anyone to take it ... although I'm more than willing to ship any mantis shrimp or predatory crabs that I find if someone wants them.
