Green Terror Fish: Aequidens Rivulatus

Green Terror Fish or Aequidens Rivulatus is a moderately large fish that becomes extremely aggressive at the time of breeding.

Going by the name of, the Green Terror Fish is frequently confused with the Blue Acara. However, compared to the Blue Acara, Green Terror Fish are more aggressive and have a more pronounced bump on their forehead. They should only be kept with fish that can fend for themselves.

The males grow to a length of about 8", and need a 55 gallon aquarium with a good filtration system. They do best in a pH of 6.5 to 7.5, and at temperatures ranging from 72oF to 82oF. It is advisable to keep these territorial fish with other green terror fish or with fish larger than themselves (like barbs). Being the territorial animals that they are, it would also be a good idea to provide them with plenty of hiding places, rocks, and plants.

Green terror fish become ready to breed once they reach a size of about 3"

They are found frequenting the sluggish waters of Ecuador and Peru in South America.

This oval-shaped fish has a broad forehead, and a compressed rear area. Some adult males even have a noticeable hump. With a greenish-white base color, the male green terror fish has red fringes on its tail. There is a more uncommon variety which has white coloring on its tail. The female is not quite as colorful.

Green terror fish become ready to breed once they reach a size of about 3". They become very aggressive at this time and so should be kept separately, in a large tank. Like other Aequidens fish, the green terror spawns on a flat surface, and may lay about 300 eggs at a time. However unlike other cichlids, it does not try to hide its nest. The female plays the role of the dominant parent when raising the fry.

Green terror fish are tough fish that are easy to take care of. These omnivorous creatures are especially fond of live food. However it is best to give them a varied diet in order to avoid digestion disorders. Pellets, flakes, bloodworms and shrimp would make up a good diet.
