Yeh they got quite friendly over the months and would come out and arm wrestle each other.

They loved the live crabs which would not even make it to the bottom of the tank before being nailed.

I think at least one of the brittle stars is still around but they don't show themselves much.

I have two large paddle crabs in my 600L. I started with four but when the females shed their shells the males carry them around mating for a few days and then eat them while they are still soft. How bizarre is that!!

I guess in a tank It's a bit hard to hide...

Nice to know the octopii did tame up a little.. They were on the root of the kelp so I couldnt guess if they were juveniles or older ones.. buy dying within a couple of days hints on environmental..

Good effort anyway WEKA.
