He he!
My red VT is active but not a bully. He swims around his domain, exploring and looking for things to munch, but rarely so much as flicks his fins at his tank mates. Sometimes there will be a flare over food but rarely, and he's never chased any of them. However, he was much less active on his own and would often sit in a plant for hours. I can just tell he's happier.
I've put some shiny pebbles on the bottom of my cambodian's tank and he just sits on the bottom, looking at his reflection. He's getting some kind of mental exercise, I guess, but he doesn't really have much to do in there.
Maybe some shrimp would be a good idea, and I like the sound of the frogs. If it all goes wrong, I have plenty of other tanks to play with.
(lol, just looked over at Orion, and he's staring at his reflection and cocking his head as if to say "well, well, who's a pretty boy then?")
