Aggression

Over the years river blackfish have had to where the tag of being aggressive I have found the opposite to be the case, it is however true if you put two ore more fish in a small container they will fight ( what constitutes a small container I have 10 medium fish in 4500 litres of water and there is no sign of aggression )  and around mating season they do become mare aggressive however this is true of almost all wild animals two lions in a small gage will fight.

the books will need to be revised and the part about aggression moderated, it stops breeders from considering these fish for aquaculture while this unfortunate tag hangs over them. To say they are aggressive is to go against the literature which says that they do not travel far from there home area( about twenty metres ) if this is to be believed then we must conclude that the tag of aggression is simply wrong.
