Arrow Crab... fish killer or unlucky victim?

[FishTruck]

So my Arrow Crab is prancing across the tank Sunday a.m. with a dead hogfish with that "...I swear... it fell off a truck!" look that they always have.

As I am deliberating over the next two days about pulling him out of there... he goes missing. Coincidentally, my Tunze quits working.

So I open the pump... and it's full of crab parts! He must have stuck his arm in there fishing for something and gotten pulled apart.

Problem solved... I guess.

Karma, Tunze style.

One of the unmentioned benefits of Tunze powerheads is they are designed to protect your fish against marauding crabs. Strange that the whole crab was pureed rather than just a couple of claws and legs. Saves you from having to act.
