Saturday night, I can hear the clicking sounds from the mantis. So I decided to check out the tank after lights out.

I ended up seeing a black crab, a brown crab (gorilla I think) and 2 small blue crabs.. upon a closer look, I think they have fans on them. Are most fan crabs blue?

Ouch
 

Watch your fingers!!!!

I know.. tell me about it :twised:

I will have to slowly take the rocks out, and catch as many as I can.

Hopefully, I can catch these SOB's when I move everything to the 200g in a couple months

Ok, so I have seperated 2 pieces of LR where I saw the crabs. It looks like the fan crabs have moved to another rock. I for sure caught the black and mantis ( i heard it ) but im not sure about the borwn gorilla crab. Those crabs are a PITA. I caught the black one with chopsticks and moved him into a plastic container used to seperate betas (its clear and hangs on the side of tanks) I guess the plastic wasnt smooth enought, because it crawled straight up and opened the top door to the container and escaped!

What is the best way to catch the mantis? I have the X-Terminator mantis trap in that rubbermaid as well.

I have read this, and it wasnt successful

thanks all

Are these fan crabs not just Porcealin crabs?? Mines blue speckled on the shell and just hides in my zoas all day long. They are good to have.

As for the mantis, all I can guess is dont load the trap till its been dark for awhile so its a little more comfortable and the food is fresher.
