yes Matty, they do as well other Parachromis species. 2 large canines at the bottom and 2 at the upper jaw.
Thus name for the Dovi (belongs to the same genus) is Wolf Cichlid.
Parachromis mostly feed on fish in the wild, so they can have good use of this weapon.

cheers alex

great i have a male and a female. i put the 2 together and they fought for hours. it was like watching to bull dogs in a match. the male won. they are apart now and beautiful as ever.
