My Tanks Come To Life Today

[john.o]

I have had my 24g nano tank for 1 week now and have had a few small problems but got through them with a lot off help off all the people on this site that are more than willing to help you out.

Over the last 24hrs or so the tank has really come to life lots of small critters swimming about. But probably the most exiting thing I have seen so far is a small crap which brings me to my question is it a keeper and what is it called

I will try to describe it as best I can. It is about the size of a 50pence has a flat back browney grey in colour with lighter spots all over its claws are wider at the bottom of its arms than at the top . its legs come to a point are lighter at the tips they also look hairy, I have seen it hanging up side down from the rocks eating algae.
Any help or advice much appreciated

Sounds similar to the one I had. It started like that and it's grown a bit and has become jet black. It's a nasty bugger. Eaten one of my shrimps already and is pecking at the starfish. Most crabs like this are opportunistic feeders - if they can catch something they will try and will eat it. Catch it if you can and take it to your LFS for them to deal with!

I was skimming this post really fast and thought it said if you catch it it will try to eat you!! Although if they could I think crabs might try!!........

I agree with Jason, get it out and identified before it causes any damage, it took me about a year to finally catch a crab which was killing things in my tank and then was only becasue I moved house and had to take all the rock out anyway, much easier to catch it now without fish / corals in the tank
