Three fish come under the common name green terror:
Andinoacara sp. 'Gold Saum' (The fish you have), sometimes referred to as the false green terror - wrongly. These fish are larger and generally more passive than its fellow species. A small number of saums have white or silver edgings to their dorsal and caudal fins - reffered to as white/silver saums. Still fall under the same species.
Andinoacara stalsbergi, The 'True' Green Terror. These are smaller than the Saums, more aggressive and have an inverted scale pattern. These are harder to obtain than saums, so you would know if you had one. They have white bands on their fins - but much thinner than saums.
Andinoacara rivulatus, a very uncommon species to the aquarium trade. Similar to the saum in scale pattern, but has the thin bands on the fins, is similar to the 'true' in size and temprement.
All three fish are referred to as Green Terrors. This is why it is always to refer to them using their latin names instead of common names.
