Id this crab

what crab is this found it in my tank
? have a fish and inverte system, is it safe to put it back?

 

Sump it, it looks a baddy.

 

got one out, there is another 1, but i cant find it? any sugestions?

 

got that one out but any sugestions bout getting the other 1 out?

 

The fish? perhaps a better pic?

 

the fish is a mollie, got 2 crabs, the one is out, still another 1 somewere

 

If it is the same as that one, remove, other than that, it will take a while to catch it.

 

yes its the same, was lucky to catch it, what harm can it do in the tank? sorry for all the questions but im a student in this awsome hobby

 

Most crabs are opportunist when they are big enough, even those that are considered algae eaters, best to remove it when small if you can.

I would point out that the crab in your tank went to bed one night and woke up, scratched , then wandered out and thought "where the hell am i? i'm bloody sure i went to bed in the pacific???" so when you remove it, spare it a thought.

 

shame the poor thing, its very shy. wont kill it , wont it die in the sump. found a creature on one of the life rock small white tenticles very thin bout 4 tenticle, every now and then it squirts out a blob of slime, do you know what it can be?

 

You won't be saying that in a month or 2 when it start eating things.

 

if you zoom in you can see the tenticles,

 

Hi Burt

I caught the same crab in my tank. The one i caught killed my Yellow watchman Goby and my Star fish. Its best to remove them.

 

ok thanx , can anybody id the thing on the life rock, if you zoom in you will see small tenticles?

 

Spaghetti worm perhaps, good guy if it is.

 

every now and then there come a blob of slime out there, is it normal?

 

It could be having a clear out
