I got myself one not long after I posted this, not sure what I think of him..My big boy is in my datnoid tank.They range in size and he mostly ignores them as he cruises around the tank.
He will get in the mood to pick with a few of them every now and then and that consists of pressing his open mouth up against them and pushing them until one of them has had enough and snaps at him and chases him off.
The smaller afer is about four inches and hides in it's cave in the growout tank most of the time.
how does it kill other fish? does it have teeth or does it just bully and stress them to death?My big Afer is a !
I have him with an Oscar and other fish an he has fought or killed everything. lol. I have had it for 6 or 7 years now and he's stunted, but will hold its own against alot! Not against my Giant Gourami however.
haha can vouch for some, my afer seems to be going that way, if he continues I have someone who extremely wants him off me, but I wont let him go until I figure out, think he might of taken chunk out of my african arowana... which is one of my most valued, at heart, fish. So if afer has done this he is going to the guy, but it could be the oscar hahaIMO most knifefish are grumpy bastards.
