The Green Terror is a member of the Cichlid family and has a tendency to get aggressive – well, with a name like that you do have a reputation to uphold. It may be a hostile fish – but it’s colourful good looks make it a striking pet. They have a blue/green glossy hue and their scales carry a variety of other colors like pink, red and purple. You can also recognize the Green Terror by the large hump on its head. In the wild you can find them in South America, Peru and Ecuador, in a domestic setting they need large aquariums and equally aggressive (if any) tank-mates who will not tolerate being bullied by these tyrants.
