It's official. I love ADFs. One day, I saw a video that showed the above fish, and I was smitten. I envisioned these fish with ADFs. But, it's really hard to get info on that particular goby (gobi??? sp?). I haven't made a full commitment to falling in love yet with this fish,yet. It's really hard to find and if you can find them, they're very, very expensive (for me). I've heard references to gobies, but never went anywhere with it. Are they (freshwater only btw), good community fish? Should I even bother?
