Hey guys. Today, I added a small royal gramma to my 60 gallon. It has 2 clowns, diamond goby, coral beauty angel, snails, a pistol shrimp. Also has gsp, tree leather, toadstool leather, a Zoa, and anthelia. I was acclimating him and the bag floated away on me and tipped over. I checker the bag and gone. Looked alllllll over for an hr. Nothing. Not even the floor. Is that normal behavior?
