Just found 2 crabs in my tank

If there not too close to your coral you can fill a turkey baster with boiling water(be careful ) and blast the hole with water. Crab legs anyone? I found a rock crab on the weekend and took the end of my alge scraper and smashed the sucker into a paste .

if you catch them post some pics! I always love seeing hitch hiker crabs, as long as they aren't in my tank
