Hmm, the Oscar is King of his tank, with the Jack Dempsey coming in a close 2nd.
The Jaguar is defintely in charge of his tank.
In my Angelfish tank, one of my medium sized Koi's thinks he's the boss.
The Green Terror Cuervo is the boss of his tank.
Hard to say in the African tank. One side is ruled by a red zebra and the other side by one of the bluish-yellow guys(Still working on a good ID for him).
The big bubble butt gold-fish is the ruler of her tank. All others are just in the way especially at feeding time.
The Pink Gourami thinks its in charge of its tank. I moved the Betta, Psycho #2 in there temporarily and he thinks chasing the Gourami and the black tetras is all the rage. I may leave him in there a bit longer as its gotten alot more interesting to watch with him in there.
Thats all for right now. I've been tearing down and re-doing tanks so I have one cycling right now, and the others have feeders in them.
Once I've recovered from my surgery I'll be back to tearing down a couple more tanks. Everyone is getting moved around so the power balances may change.
In my goldfish tank, Neo is the Kingpin. I think all the other 29 or so goldfish got tired of him swimming around with his nose up their butts that they figured: "Ok ok ok you can be king!" In my tropical tank (#1) it's Billy, my giant male tri-spot gourami. He pokes fishes eyes out with his feelers....it's quite a sight. 
THen there are my many many Betas....Oh we won't even go there. lol In my 200 gallon, Zim and Gir, my two massive, and new, albino Tinfoil Barbs are kings. THey share the throne. Not even my male oscar (who is also new) Blizzard can compete.
