Well, just got back from the coast with about 30, inch or so sized crabs.

Does this size sound about ok for a 15cm (full length, 10 cm mantle length) cuttle?

Also, i have collected some sea water to go with them, but thinking about mixing this half and have with synthetic salt water - anyone see any problems with this?

perfect, its better to use sunthetic salt water as sea water has a lot of plankton etc that will die quickly in a tank poluting the water... best use a 100% synth mix.

That will keep a cuttle quite happy for a week or so :smile:

Have you got the cuttle yet? (this friday?)

Can someone please tell me about the mechanics of feeding a crab please!!

I take it i chuck the crab in live, the cuttle catches it, then what happens??

The beak cracks the shell and eats the inside? It just cruches through the whole lot - shall and all?

What gets left - do I remove it? etc etc.

the cuttle injects venom into the soft joint of a crab and kills it... if it a small crab it will just get munched, put your ear to the tank for some pretty nasty bone crunching noises LOL

The cuttles are quite wastefull, they eat the soft part in the carapace and most else get spat out, that why you need a good clean up crew and you should also remove uneaten food as soon as you can, left over ood will polute the tank quick and carapaces left in for a while increases the phosphate levels in the tank...

also, dont panic if you see the cuttle blwing out little disks at an time, they shed the skin of their suckers quite often

I got a nice gren brittle in there, and also normal reef clean up (hermits and turbos).

But the clean up crewe will probably get eaten wont they?

Not by a cuttlefish, it will always try and pick up new things you put in to see if it is food, but i had quite an army of hermits and they all did fine with the cuttles :smile:
They cant get them out of the shells like an octo can..
