well it seems to be going back and forth between looking fine and then not so hot. I have no idea what is goind on. Yesterday I left to go to Gary's and it was fine, then I came home and it shrank again, could something be messing with it? Inhabitants are Maroon clown, engineer goby, various snails and hermits, emrald crab, sally lightfoot crab, 2 peppermint shrimp, Zoas, xenia, and green star polyps. I dont think any of that would effect it but Im a rookie.
