Ok, maybe not the best full tank shot, seeing as my tea cup is in the way, but it was holding up the mirror for Alfred. This is my new 5 gallon for my betta, Alfred. After setting up a new tank for my son's betta, Jupiter, I wanted more space for Alfred too. I lucked into this tank second hand and went with black gravel and sand. He's got a sponge filter, tucked behind some silk plants. He has a ping pong ball that he likes to blow bubbles around and a sabre-toothed rat skull to hang out in. When he sleeps in the skull, his tail flows out of the mouth... It's both funny and disturbing.
Here's a video of the tank:
