i have dealt with large and agressive predators for almost 40 years, fish and animals
and there are exceptions to the norm, it is all dependant on personalities of the animals/fish involved, oh and the people
there are ways of diverting agression but no one way is the standard or the perfect answer
these are goood rules to follow
sometimes these big fish if owners can't find a home will be destroyed
it is always worth taking a chance on homing them
but make sure there is a backup or they can be seperated
