Alright, who do I have to kick out of my tank??? 40 gallon AIO. A couple of weeks ago my blue coral banded shrimp that I've had for 2 years was mangled, then the next day was gone. Last week, one of my conch's was gone. I've had a pair for over a year. Today, I noticed that my anemone crab that I've had for about a year is missing. The newest additions to my tank are a pygmy hawkfish and an orchid dottyback, both added a couple of months ago. I know, hawkfish eat shrimp, but the coral banded shrimp was 3x it's size! Do hawkfish attack snails? What about the dottyback. I know they hunt bristle worms, but a crab? What gives? Any tips would be appreciated, I'm in fear of losing my blood shrimp next. The shrimp is huge, but the way things are going, I don't like his chances.
