thismorning when we got up and turned on the lights our lg crab was on 5 of our small crabs... all out of there shells and some had limbs removed... did he kill them? or was he just cleaning? i know some had just finished molting.. and now this... my last small guy has burried himself and i am afraid to dig him up to see what happened...
any advice?

he was definatly not cleaning them, I am almost positive that he was attacking. iso him away from the others immediatly. what kind of conditions are the others in? its possible that one or more of them could survive the stress of an attack, even with missing limbs.

If there had been recent molting, then the smell could have attracted the big guy to the little ones. I had that happen once, and when I caught the fight, I bathed all the crabs in the same water bowl so that they all would smell the same. Haven't had that problem since. I wouldn't dig your little one up though. Just keep an eye on things if you can't ISO the large crab.

Sorry that happened to you.

Do you have plenty of non painted shells from them to choose from? If not the big crab could have ripped the other crabs out of there shells because he wanted to see if they were big enough for him or like the other people said he could have just liked there smell and went crazy.

Sorry to hear.

It could be territorial issues also, 7 large crabs and 6 small in a 20 gallon is may be a bit much. In a 20g you should have 3 large OR 4 medium OR 9 small OR 12 teenie IMO. You may want to consider upgrading or dividing them into two tanks.

I agree with the too many hermies in a too small tank. I'd split them up if you are able to, or maybe adopt half of them out?

That is my worst hermie fear. I am so sorry for your loss.

I have a sm-med PP who is just nasty premolt. He has attacked larger crabs before he went down to molt. He took chunks of a BP on two of the larger crabs. He was nasty for over 6 months. When he finally came up from the molt he was cranky but not aggressive anymore. It helped when he went into iso. I think it gave him the quiet he needed to pull off the molt.
I am so sorry for your loss. Hope your little one is ok.
