Cons: sometimes hides in the sand
Our fighting conch, Larry, is by far my most favorite critter to watch in our tank. I can sit and stare forever watching this cool little guy. He's great at cleaning with that long snout of his and I love seeing his little eyes. Though we were told they tend to keep themselves buried ours is out most of the time and only buries into the sand occasionally. He's certainly not shy and is often right at the front of the glass. It's like watching a little vacuum cleaner as that long mouth goes over the sand. He is also great at helping to keep our tank clean. Every once in a while he ever tries to climb the glass, but never seems to get very far.
