Will a shrimp Kill and eat your crabs?

The shrimp is eating the dead crab. It didnt kill it its just cleaning up.

Well it is a banded shrimp. I was thinking of a cleaner shrimp. If you arent feeding your tank enough then this guy might get a bit aggressive. How is your snail and hermit crab population doing. Are they dwindling as well?

You should feed more. IMO. I feed a mixture of frozen every day. Something else to check for would be a rock crab. If youve never had more than 3 snails then thats probably not it. If the shrimp is hungry it might be turning to anything it can catch. That would include your hermits and snails.

You definatly do not want one. I tore a tank completly down to get one out. They kill your hermits, snails and in my case my prized manderan. They usually are brown in color, They can be red as well. Usually they hide very well and you only notice them by chance.

I target feed my shrimp everyday. . with a turkey baster full of bbs or mysis.  He's molted like 3x in the last couple months.  

Yeh that's what I feed him.  I know his usual hang out and I take some in the turkey baster ($1.00 @ Walmart) and I shot some in that direction and you can see a red flash scurring around.

And then I feed the rest to the clown & Wallace. . . no biggie really.

Ya I am sure it was the shrimp as when I first caught him the crab was still semi alive.. There was nothing I could do to keep him alive.. 4 legs had already been eaten/torn off and the back of his head was exposed.

ok cool looks like I get to do some shopping
