Are we doing predatory/aggressive or just aggressiveness? Most of the fish we are naming are more predatory then aggressive but still some what aggressive. Where do we draw the line between predatory and aggressive? Seems like a pretty blur line.

That is true it should be like this
Fahaka AGGRESSIVE: to fish it's size even bigger than it,aggressive to other fish and own species,aggressive to anything in the tank
pike AGGRESSIVE & PREDATORY: aggressive to other fish bigger or smaller and even some small animals,predatory while bieng aggressive
SNAKE HEAD AGGRESSIVE/PREDATORY: to watever it wants to eat,predatory to fish it's size or smaller
now someone else try it
Matter of fact my vote goes to the fahaka in every way imaginable
If you want to know the def. Of aggressive it's fahaka,think about aggressive to it's own species to every fish any living thing in the tank with it,soo aggressive you can only keep 1 while other aggressive fish u can keep with other aggressive fish doesn't sound too aggressive does it an aggressive fish tolerating another living thing in it's tank,fahakas too aggressive that only in the wild it could be bred that's my vote

But there are lots of species are very similar to Fahakas' behavior as well...Black piranhas and other piranhas fit this behavior. However I've seen fahaka and mbu puffers swimming with small schooling fish....

Some African cichlids are very aggressive and some aren't. It just depends on the sp.
Hejetas are more preditory. They kill their prey by biting and chewing on them. They will ever attack larger fish then themselves.

Piranhas aren't in this list because they are really skittish.
 
Yet you can't keep anything with them..duh!

I know you can keep anything with them, im not stupid. But, my piranha is very skittish. Of course, you can't put anything in with him but goldfish are more brave than him.
 
texas should be there, a new bankrupt aquarium outlet had an aggressive 180 display tank with jags, sub-adult Doviis, JDs red devils, and about 4 other rather large CA cichlids, though one might have been a fader flowerhorn didn't know, a 14 inch ornate and an 18 inch arowana. All of the cichlids were over 9-10 inches aside from a single 5 inch texas. after a week of everyone gang banging the texas the owner was about ready to remove it. The day she was planning on rescuing the texas she came in to find every single fish shredded to the point of near inability to swim and huddled in a corner except for the bichir and the texas, who was swimming around the whole tank. eventually the others recovered but that texas always seemed to have half the tank under his control from that point on
