I'm really starting to get frustrated. I was having some minor brown algae issues so I wanted to get something to keep my tank nice and clean. I first purchased a bi-color Blenny and after a few days, I saw my hermit crabs having a feast on him. Just this week, I added a Diamond Watchman Goby and just walked by my tank to see him being feasted on as well. I know hermits are opportunistic hunters, but can they actually kill your bottom feeding fish? I figured both of these guys could get away if needed. If that's the case, I'm going to take my hermits to the store and go only with snails. Would appreciate your feedback. Thanks.
