My boyfriend has a 46 gallon tank and he put in a Lawnmower Blenny that I thought was the coolest thing ever. He was not so hot for it but he put it in for me. I went out of town for a week and he dissappeared! I was thinking maybe he returned him since he was taking up valuable "fish space" but he claims that he must have been eaten. Here is what he has- an anemone, yellow tang, blue tang, clown fish, cleaner shrimp (skunk?), some corals, hard and soft, and a bunch of blue hermits and turbo snails. He was not in any of the equipment- I looked everywhere. Did these other animals eat him? The yellow tang was always trying to hit him with some spike on his tail but could that have done him in? Or did he really just return him? Thanks.
