My lil old man is probably three years old now. I'm always amazed at his level of activity. I gave him Floramax gravel yesterday and removed him from his tank to do it. I switched a few things around. When I put him back in he was all over. Today he's a feisty maniac.
Here's his tank:
Here he is, chillin between maniac runs at the filter (you can see that growth at the base of his pectoral here. It makes him hold it funny but you'll see in the video, he's learned to use it just fine)
And here's a video of just how active he still is:
It's set to Tango Curiouso, which is perfect. :D
