Oohh noo I knew it! I added a red pistol shrimp to my tank to buddy up with my watchman goby but it didnt go as I planned. The shrimp went into the goby cave and kicked him out now my two cleaner shrimp are missing and a cleaner wrasse is missing both its left and right fins. Ive been hearing the pistol shrimp all night long every night. I had a hunch that he was the cause of this. seeing this video confirms it.
What should I do? should I tear donw the rock work and get him out? That sucker is about 2 inches long.
