I was finally able to trap this creater in a crevis in one of my base rocks ( i.e. 2 months ). :yay: That's where he will stay. I plan to use some epoxy to close the hole in the base rock. I'm going epoxy another rock to the base rock. I don't want to pull out the base rock to remove this crab. Has anyone used epoxy in their tank? Or will epoxy contaminate the water? If know one has used epoxy, does anyone have a recommendations. Thanks.:thumbs:
