Two days ago I bought a cleaner shrimp for my 20 gal. He has been wandering around and eating here and there so I think he's in good health. I read in lots of places that they like caves, but the one I bought seems to love hiding right in the open under my new GBTA. Is this normal behavior and is it anything I should worry about? PS- all the shells aren't from dead things I put them there because my hermits are evil and switch shells like crazy.
