Castiel, my lovely white VT male, apparently does not like invaders. He is in temporary housing until I figure out how NOT to kill plants, and has been doing pretty well. Today I decided to add a few bits of duckweed into his tank, just because.
The little devil went and tore it all up! Now I'm half afraid to put him in a planted tank!
I'm pretty sure this rules out any and all tankmates, except for maybe a snail. I knew he was aggressive when he started stalking/attacking his food, but oh my, the little guy has anger issues.
