Amatitlania septemfasciata (sometimes called the Seven-stripe Cichlid or Cutter's Cichlid) is a fish species in the cichlid family. It is found on the Atlantic slope of Costa Rica, between the drainage and the Banano River.[2] Several currently recognized cichlid species within the genus Amatitlania were formerly considered varieties of Amatitlania septumfasciata, including , the Topaz Cichlid, and (which also sometimes uses the common name "Cutter's Cichlid").

Prior to being placed in the genus Amatitlania, it had been considered a member of the genus Archocentrus.[3] Within Amatitlania, Amatitlania septemfasciata is placed in the subgenus , along with the T-bar Cichlid and several other species.[3][4] However, a 2008 study led by has suggested that all the related species A. septemfasciatus, should be moved into the genus Hypsophrys.[5]

Natural history[]

Amatitlania septemfasciata grows to between 4 and 5 inches (10 and 13 cm).[6] Males are typically larger than females.[7] Both sexes generally have six vertical bars along each side.[8] Females have a black spot or ocellus on the dorsal fin, which is generally surrounded by metallic coloration.[8]

It lives in rivers on the Atlantic slope of Costa Rica.[8] It can be found in rivers of all velocities, including slow moving and fast moving rivers.[8] The bottom of the rivers it lives in are generally covered by rocks and leaf litter.[7] In its natural habitat, the pH is generally between 6.6 and 7.6 and the water temperature is between 21 and 27 degrees Celsius (70 to 81 degrees Fahrenheit).[8] Its ability to protrude its jaw 3.5% standard length limits its diet to about 1% evasive prey.[9]

Amatitlania septemfasciata is an egg layer and a cave spawner. In breeds in crevices in the rocks at the bottom of the river. Spawnings typically result in 200 to 250 fry.[8]

The conservation status of Amatitlania septemfasciata has not been evaluated by the International Union for Conservation of Nature (IUCN).[2]

Aquarium keeping[]

Amatitlania septemfasciata is kept in home aquariums. It is territorial, and thus a fairly large tank that is at least 90 to 100 centimetres (35 to 39 in) long is generally recommended.[7][10] It can be kept at a temperature of between 24 and 26 degrees Celsius (75 to 79 degrees Fahrenheit), and pH of about 7.0.[7] In the home aquarium, it is willing to eat a wide variety of foods, including flake food, live foods, frozen foods, beef heart and shrimp.[7]

Amatitlania septemfasciata can be bred in the home aquarium. It will either spawn in a cave or in the open.[7] A temperature increase to 26 and 28 degrees Celsius (79 to 82 degrees Fahrenheit) helps induce spawning.[7] The larvae hatch 72 to 80 hours after spawning, and are free swimming after 180 to 200 hours.[7] The parents do not eat the fry, but rather both parents care for the fry intensively.[7] The fry eat newly hatched brine shrimp.[7]
