Put these fishes in separate tanks and then starve them for weeks....then put your hand in and you'll know the winner

Okay, Lets get down to Business! The most aggressive Freshwater fish I ever had; and still have is the Elongatus Piranha (Piranha Serra Elongatus) He will follow my finger and everytime I go to feed this guy, he will try to jump out of the tank. He kills everything in the tank and is not shy! Very cool fish to have, however I am looking for a bigger tank for him, maybe a 240g.

i would say it was none of them, and it def aint most sp. of pirahna, esp. red bellies

out of all the fish i have ever owned. the most aggressive would have to be Redline sh. and the golden pirahna(not sure of latin name).

Define aggressive, do you mean among themselves, tank bullies, fish killers?
The most homicidal fish I ever owned was a 6" Phago loricatus (used to be maculatus), as you can see it is pencil thin. it killed about 30 guppies in about 10 minutes, it only ate a couple of them, the first night I had it it ripped up a healthy 8-9" common pleco so bad I had to whack it, the Phago had blinded it, sliced off all it's fins and tail, and slashed open it's abdomen badly enough tha you could see intestines. I don't know if it was typical of the species or just nuts.

Yep Guppy thats mine. It was starving its self after eating parts of its mate and killing it. It ate one wax worm then nothing for 10 days but has just went mental when I put some blood worm in thrashing about till the last had gone, 1/2 pleased to see it eat but it will have to remain by itself.
All the best,
G.John.

I agree with the snakehead being the most aggro... I watched my two toman snakeheads bite a female flowerhorn, one bit the head, and one bit the tail.. And they did opposing crocodile death rolls. This ripped the fish in half. I tried for days to get them out of my pond with a net, then after some trial and error, i finally got them out.. With a bass lure. It was actually fun.
