So I got an engineer goby a few years back and he was perfectly good back then as far as burying things and now he's swimming around the whole tank burying corals and some rock work. Is there anything I can do to revert him back to his old behavior or do i have to give him to the lfs so he can find a new home who likes his behavior. I used to love him but as he got big he became awful, nobody told me of this when I first started out, but that was when I got my fish at petco :/.
