Bristlenose Aggression Problem!

[rocknurworld2006]

Hi i have this bristlenose which is a male but is smaller species than the common bn you get not sure exactly what though?

but anyway he is not quite a year old yet and is extremely aggressive ive had to move him about 5 times now from tank to tank, as it attacks anything from corys, to even seen it attacking tetras?

this is so strange as none of my others are aggressive.

so i moved it today into my 5foot malawi tank, i already have 1 adult big male and 2 adult females

the aggressive bn is half the size of the adult male, and smaller than the females, so put him in and he got into a fight straight away with the big male, who is usually very peacefull!

will he be ok in here or can they cause damage to each other i dont why he thinks he is so tuff as the adult male is twice the size of him.

there is plenty of hiding places as its rocks for malawis.

is there any advice you can give me on why he is like this and what i can do if anything, every tank he has went into he causes trouble!!!

That is horrible.
I really hope someone that knows more than me comes along very soon.

For now is there any way to put him in a tank alone?

I have three and they sometimes fight with each other but it never spills over to other fish not even my other plpecs. very strange and it must be a rogue fish. all I can think of
