This send looks to be a handful. I couldn't say all sens are aggressive though
This one is also an old video of mine I almost deleted. Unfortunately in the UK, Senegals like this are all too common, we almost never see wild Senegals and not often quality cb Senegals, just really inbred ones.
The aggression was just because it was horny, there was constant failed cupping for the last weeks before I sold him, that the area around his anal fin became swollen from lack of relief.
(Bichir equivalent of blue-balling really). The fact it was so inbred may of been a factor into aggression or even why it couldn't release any sperm. To top that off, it has a growth under its eye which looks like pop-eye; I know that'd piss me off too.
It was stressing out all the fish, even the African Arowana at this point. The Ornate would scrap back and it kind of looked like a normal
pecking order dispute.
For more info on what those are, have a watch of this video
