| Origin | Ecuador and Peru |

| Compatibility | Territorial, aggressive - keep with fish of a similar size and temperament in a very large tank
(more than 100 gallons), or with robust shoaling fish, such as larger barbs. |

| Comments | Two colour varieties of the Green Terror are recognised: one with white edges on the tail
and dorsal fins, and one with yellow/orange edges. The species known as 'Green Terror' in the aquarium trade is not thought to be the
true Aequidens rivulatus, but a closely related species. |
