Its been about 6 weeks and the lobster hasn't killed any of my fishies which is GOOD. They seem to be getting along just fine. However he's been digging the deepest hole under some live rock and appears to be on his way to China. The main problem other then the rock possibly falling on his head is that the tank has gotten very cloudy from all his digging. At least I'm pretty sure thats what the cloudyness is from. The little bugger won't stop digging. What do do.... what to do.... Maybe he'll stop eventually? hmm.
