Don't lable the whole breed, Cause as we all know.. Each and every fish has their own unique personality.
I have 2
CAE, as can be seen in my sig.
The bigger one, thats in my 29gal tank, Is only aggressive at food time. And even then he's only aggressive towards the Bala shark. Its not even serious aggression, Just chasing the nosy bala away from his food before turning around to eat.
THe smaller
CAE in my 10gal tank, it is the sweetest fish in the tank. Calm, Placid, a big baby. It has absolutely
NO food aggression, No aggression AT ALL. He does not bother the other fish in the least.
They are algae eaters when their young, as they grow their interests drift from Algae to other types of food.
Sure, there are the mean CAEs who live for no other purpose but to attack and kill everything in sight.
But
IMHO its wrong to lable ever single last
CAE in the world as Murderous Monsters.
I'm not saying Kan's
CAE is not aggressive, I'm meerly arguing the generalization of them being evil.
