Jack Dempsey Overview<\/h2>\n

The Jack Dempsey\u2019s scientific name is Rocio octofasciata. This species is part of the cichlid family and lives in the freshwater streams and rivers of Central America including Mexico, Belize, Guatemala, and Honduras.\u00c2\u00a0It can also be found in parts of the United States, Australia, and Asia. However, it is considered an invasive species in these areas and likely came into existence when aquarium owners dumped their pets into wild waters.<\/p>\n

You\u2019re probably wondering where the name Jack Dempsey came from. Jack Dempseys are named after an American heavyweight boxing champion in the 1920\u2019s,\u00a0William \u201cJack Dempsey\u201d Harrison<\/a>. Dempsey was considered a heavy hitter which aligns with this Cichilid\u2019s archetypal body shape and semi-aggressive tendencies. However, with the proliferation of cichilds available on the market now, Jack Dempseys are more mellow than some of the more aggressive species such as Jewel Cichlids<\/a> or Jaguar Cichlids<\/a>.<\/p>\n

Jack Dempsey Appearance<\/h2>\n

Jack Dempseys are beautiful fish. They have a typical oval-shaped cichlid body and are longer than they are tall. They have pronounced facial features as one might expect from a heavyweight boxing champion.<\/p>\n

Part of their popularity comes from their variety of potential colors. They range from a dusky, rosy pink all the way to a dark, almost black color. There are multiple varieties (see below), but the most popular options are typically golds, blues, and pinks.<\/p>\n

\"blue<\/figure>\n

Their color changes as they age with younger fish being typically less vibrant. Expect to find younger fish with a pale grey body with green flecks, while older fish become a deeper purple-gray with bright blue-green flecks. Additionally, their colors change depending on their conditions. If they\u2019re stressed, they will get pale. If it is mating season, they will get darker and more contrasted.<\/p>\n

Color Varieties<\/h3>\n

Electric Blue <\/strong><\/h4>\n

Electric Blue usually refers to the Blue Acara, an African Cichlid<\/a>. But the color variety doesn\u2019t stop there! The Jack Dempsey also comes in Electric Blue. An Electric Blue Jack Dempsey is a bright neon blue, with black spots. This color is the result of planned breeding and does not occur naturally in the wild.<\/p>\n

Black Blue <\/strong><\/h4>\n

As the name suggests, this is another variation of blue Jack Dempsey. Their body is usually black or dark grey and they have a sprinkling of iridescent blue or purple spots. While this color variation can occur in the wild, it is rare.<\/p>\n

Other Color Varieties:<\/strong><\/h4>\n

With these species, there really are an abundance of vibrant hues. Some of the other popular color options include:<\/p>\n
