Hi! I've had a lawn mower blennie for about 6 months. At first he was shy but eventually started cruising and normal blennie behavior. Lately he has retreated, hiding, and at night sleeps at the top of the tank wedged by the filter.
I have since added a watchmen goby and pistol shrimp - bonded and cohabitating nicely ! Also relatively new - my suspicion - is the addition of a small purple reef lobster. The LFS
assured me the lobster is peaceful. Was I duped? The blennie is good sized in comparison to the lobster. I have lot of LR
No other trouble makers in the tank. Thanks for any help!
