Title says it all, I recently lost a clown for no reason I dont know if he is the culprit but I have actually witnessed him pick up an entire frag and try to pull it into his rock. Hes about 8 inches when hes out of the rock but never comes all the way out so I know theres a few more inches hiding. Do I absolutely have to remove the whole rock or is there another way to get him? Hes been in the tank for 6 months or so and hasn't been agressive till now, I even have 5 thor shrimp he hasn't eaten yet (knock on wood). Thanks for any help in advance
