Hi everyone, newbie fish owner here.Several months ago, I rescued my violet goby Houdini from his previous home (which was horrible). He's been doing much better since then, though I had him living on gravel for a few months. Finally, I was able to change the gravel and get him some sand. I know his tank is a bit small, I do plan on getting him a larger tank once I'm able to. However, he seems to be enjoying it, and since I got him he's grown about an inch!
