You do know you could be reintroducing them into your tank when you remove the crabs and put them back in, if they happen to be on them. I did that in the past and they came back next time I didnt put the crabs back and have never seen them since
thanks for that info Ray, i was planning on removing them as well but looks like i wont. how bout a cleaner shrimp though, think theres a chance of introducing them back in from a cleaner? i could always QT him for a bit.
