This is just a picture tank. Its an old betta tank really. This fish is in a 20g planted by himself, with a filter. He's new to me and still too shy to come out of hiding when I'm around. I actually just had a breakthrough Friday when he started recognizing the food container and coming to the top of the tank for foodwhen I tap the lid. Other then that he still stays out of sight for the most part when anybody gets within a foot or so of the tank.
