In saying the above, he's a cool "cat"....so to counteract this perceived issue I will add some african cichlids into the tank.

Oh and by the way the tank is a Juwel Vision 450 (litres) so ample space given he would be 8-10cms long.

Can we mix african and american cichlids????

Cheers all.

Thank you all for a great insight. It is greatly appreciated. If u r adamant it is the species u say it is than who am I to disagree. It certainly puts my mind at ease.

Im in Melbourne, Australia so Im none too sure how common/uncommon these species are.

Again thank you greatly.

As per my subject heading. Please note this pic doesnt show his sail fin when it is up.

I'm curious to find out as we have had other fish in the tank but gradually they have moved on and I'm suspecting this guy I have is bullying the other occupants.

He is a tough bugger and lives can live in ...
