    Morning guys ...

    A few weeks back i discovered a little crab in my tank ... and wow, it is like a damsel, but only more @#$@#$@#$ ... it is destorying my tank, meaning eating up what it can. He took out recently 2 clams ...

    What can i do ? I know catch it right ... but wow, he is so fast, and he love live rock to hide in

    :(

    Zerocool, I had 5 crabs in my system.

    Some people use the cut off coke bottle trick with some calamari or other suitably crab interesting meaty treat. It didnt work for me. I had one particular rock that was easily accessible (for me) in my tank. I got up every morning 10 minutes early and peered with a torch to see where they were hiding. Every few days one would be seen on this rock so I'd simply reach in, grab the rock and then poke and prod until said crab scuttled off into a plastic container. I sumped all but one who I sadly had to spear with a screwdriver.

    Goodluck!

    Lean a glass up against your LR and put a piece of hake or something in in. 15 min after lights out you'll have the bugger... Caught the same crab twice in two nights with this method... :biggrin:

    what i did was pull the live rock a saw mine dissapeared into .... and then try get him out. if he is hiding in some rock that has no corals on it, this would seem like a sensablie approch rather than trying to catch him in your DT.

    The problem is once you start fiddling too much he goes into deep hiding... The glass method is the least invasive and he feels comfortable going for the bait... I seriously did not spend more that 15min two nights in a row catching tha same bugger... First time I put him in the "sump" at the back of the boyu and somehow he made it back into the DT so I had to do it again the next night... :biggrin:

    I have 4 in my refugium.

    Lifted the rock it was hiding in, and held it above the refugium. They try to escape back to the water, so they jumped by themselves.

    Need ID on him fast. I think he's bad, but don't want to dispose of him if not. Pointy claws. Here's a pic.
    (I didn't have a small enough drinking glass, so I cleaned out a spice jar that had had parsley in it.) Added some mysis and turned off all lights. Really worked fast! Nice trick there. (Too bad it won't work on my wrasse...)

    Nice site Belinda,
    But its for cold water species
    But if you look under anemones, there are some cold water species that is just too beautiful. And just for you, even some pink ones.
