The Rare and Aggressive "Guppy"! LoL:ROFL:
 
Why isn't goldfish on there? You should see mine tear into a shrimp. They're like underwater pitbulls. They even shake their heads all over the place like them. They're ferocious!
 
that is a silly list of aggresive fish almost all if not all of those fish are just feeding not being aggresive. An oscar swallowing 2 dozen goldfish doesn't make it aggresive IMO.
 
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.

4 threads for 1 topic is excessive.

I can't believe that thing tore up a pleco that big that easily. I say that thing wins, it isn't killing to get food, it's killing to kill. either that or guppy's fish are just holding there own little fight club. haha!
