I have this crab that came along with my LR. When i added a clean up crew the other day, he killed a hermit and a snail within one day. I needed to get him out of there before he killed more! He was fast though an i couldn't catch him. So i posted on here and Brenden said to put some bait in the bottom of a glass to try and trap him. I first chased him into a hold on a piece of rock and them removed the rock to my qt tank. I then took a cube of brine shrimp, perferrated the top foil cover and used some aluminum foil to strap it to a martini stirrer. I dropped the whole thing into a glass (made of glass) and tilted it up on the side of the rock right next to the hole where i saw him go in. I left it there overnight to see if he'd go for it. Sure enough, i woke up this morning to find my killer crab trapped in the bottom of the glass. Hahaha...gotcha sucka!!
Are those additives for the tank 8O
