Greetings. I bought a Diamond goby today and introduced it to my tank. Acclimated for about 1 hour, and all my levels are where they should be. What could be wrong? It stays in one place, and when it decides to move, it try to jump out of my tank. I have no idea if it matters but the lady who bagged the fish had taken water out from a different tank that the Goby was not in, wasn't there as I went to go grab my wallet from my car and my gf had told me as the lady was bagging the fish.
