It's a really bad pic, but the only one I can find. His colors were really muted when I got him, he looked anemic, lol.
Beezle, he's in a 5 gallon hex by Marineland, and the filter came with the tank. I got it at Petsmart. I planted it with a good handful of plants, and he just loves it. I have him at work, and most of the office stops by to look at him, and see how he's doing. He has a ton of tall leaves to lay on, or one of those worthless betta leaves stuck to the tank near the top, but he prefers to lay in the gravel. Weirdo.
This is the whole tank. It is plastic, as evidenced by the scratches. I had a co-worker watch my tank when I was out for surgery for a month, and I think she took a brillo pad to it! But all in all, I love it, and have had no problems with it. I do have an extra light I shine on it for a couple hours every day, so my plants get enough light.
