It is really tough to get that pic. When I first spotted him in there you could barely see his head. As soon as I grabbed the cam and got it ready he spotted me and made his way out. He gets excited and always swims out to see me so it is really hard to snap him when he is fully inside the gullet.
Yes, it does blow bubbles, I disabled it though because they were really not what I expected. I guess I could have stepped up the pump and I can always rig it with an airstone but for now I think I prefer it as a simple deco.
