Rufus's vase-thing makes me sad. It's so small. =( Betta should as least have 1 gallon of space. He's swimming in circles because he's bored and has nowhere else to go.
Oh, and for Bubbles, I suggest using a cup to scoop him up with as opposed to a net. As you see, they can get caught in the net. =(
Anyways, here's my guy, Kisame II.

Boo welcomes Kisame II home. Later info reveales that while the tank is cat-proof, his cup is... not. Boo almost knocked it over. She's very interested in this fish!

His tank is set up! Hornwort plants and a hamster tube T-joint for a cave.

Kisame and his bubble nest.

Close-up!

And lastly, Kisame I. R.I.P.
