Spider Crab?

[divemonster]

Here is one of the oddest crabs I have seen yet. It looks a bit like an arrow crab but behaves like a decorator crab. I've looked at some ID stuff and "Spider Crab" was the closest ID I could find. Since being in the tank it has added red algae and Caulerpa to its "head" and legs. It's carrying its own garden on one of its legs.

Wow...now that's definitely an interesting little guy...perhaps he's just an anorexic decorator crab that's watched too many gossip shows on tv with Paris Hilton?

If it starts decorating itself with pink coralline algae then we'll have to pull its TV privileges!

It definitely looks like an arrow crab to me... Do any of the arrows decorate themselves? Red could be right, its sp. Parisa Hiltonia!
