Both of my fish are pretty goofy.
Vardaman is a weirdo. He's totally hyper and strange. When it's near feeding time and I walk up to the tank he will open and close his mouth. Haha. But here are his weirdo moments caught on camera:

Here he decided to dive bomb when I took out the camera.

Here he is squished upside down between the tank and his feathery plant.

Here he squeezed himself between the tank and the back of his mug. I didn't think there was enough space for him to do that!
I only have a few of Algernon being weird. He tries to eat everything. One day he started flaring at the snail and spit a piece of snail poop out onto the snail. I saw him repeat this the next day. When I added java moss to his driftwood he tried to eat that too.

Here he was obsessed with his heater. He spent all day sleeping by it for days.

And here he's just being creepy. Creeping at me from over a leaf.
