So I have two bettas in a (divided) 10gal. The filter is see-through, and the fish that share it (Promise, a red/blue/purple crowntail, and Bullet (a red/white doubletail) (both males) have two very different personalities. Promise is aggressive, pompous; he spends a lot of his time flaring at Bullet. Bullet is my sweet, shy guy who likes to hide and never flares. So in my dream, I come out and see that somehow, Promise has gotten past the divider and was having at Bullet (seriously, the guy has no chance). I ran to get the net and separate them, but it was too late.

And yes, I know it was a dream because I made sure to check when I got up this morning. Sorry for boring you with my dream; I just wanted to share this.
