Most aggresive fish ?

I think that some people here are confusing aggression with predatory habits, which are completely unrelated. Just because a fish eats another, it doesn't mean that it is aggressive.

 

Very true Salmon, although most of the fish I've seen that eat other fish tend to do it very aggresively!! Lol! They also tend to think that your fingers are fair game too!

Most aggresive fish I've ever owned was probably my Cacatuoides Female when she spawned in the community tank! She chased off fish 5 or 6 times her size with ease!

After that would have to be the Chinese Algae eater I bought when I first started out! Chased and terrorised just about every tank occupant, often for no reason!

I'd have a good laugh if someone called my Shovelnose aggressive
