The arrow crab was far away from the snail when I turned on the light. It's not the arrow crab. Arrow crabs are scavengers and I had fed him the night before.

There was something on the snail, I just don't know what it was. It was too fast.

I am guessing that you have another crab in there that you didnt know you had. Try and get a good look at it. Be prepared before you turn on the lights

Any way for me to setup a trap or anything? I could round up my snails overnight in a plastic container and setup some food for it.

Yeah you can try and trap it using a bottle and bait.

When I moved my crabs + snails from the old tank to the new one I caught most of them by hand but I wasn't sure if a few stragglers were left hiding in the sand, so I set up a little tupperware in the tank, covered in bridal veil with a little slit in it so if they were persistant enough they copuld get in, baited it with frozen fish food and waited till the next morning. 4 crabs and 2 snails!

What do you guys use as bait?

Keri · #17 01-15-2009, 07:50 PM

Just a chunk of frozen fish food, weighted down with a little bit of rubble.

Arrow crabs are NOT scavengers. you may get told that but in my experiences they like to try and catch fish and will prey on most anything that is slow and cant defend itself.

Guess a girls gotta do SOMETHING with the old bridal veil.....

I would think it most likely that your arrow crab did the killing and then whatever you saw dart away when you clicked on the lights was the actual scavenger...
Just my best guess.

This sucks. I'm gonna try trading him for some shrimp or a red sea star. If anyone is interested, let me know.
