Fish Data : Lionhead Cichlid



 The adult male Lionhead Cichlid has an imposing air about it because of its huge humped forehead. No matter what you find the Lionhead Cichlid called, all the common names are descriptive of this prominent nuchal hump.

  The Lionhead Cichlid is definitely a unique addition to your tank. Simply looking at their picture gives you some quick clues as to the special characteristics of this fish. They seem to perch on the bottom and their movements are similar to gobies where they tend to 'hop' or 'jerk' from place to place rather than swim. This is because they have adapted to the fast moving streams of their natural habitat. Their lower fins act as struts for support and their swim bladder has been greatly reduced, which keeps them from readily floating and then having to swim against the current.

   This is a fairly small cichlid, generally reaching only about 4 1/2", and is moderate to care for. A great choice for any cichlid enthusiast who has limited space and cannot provide a large aquarium. The Lionhead is not demanding about the pH and hardness but it does need very clean, oxygen rich water. Doing 30% to 50% water changes every week, depending on fish load, is important. They need a lot of caves near the bottom of the tank for retreating, several places at varying intervals work well. They do not bother plants, which is great for those who like their aquascaping. Provide plants that are hardy and individually potted.

  The Lionhead Cichlids are peaceful little guys. They are considered to be a community cichlid if kept with the right tank mates. Generally they will get along with small peaceful fish that are not bottom dwellers. They do best in a species specific tank and can be kept as a pair, but will not get along with other conspecifics. They will often pair for life and remain solitary if their mate should die. Like other cichlids they become territorial, especially toward conspecifics, during spawning.

zed head, and blue eyes. The male develops a nuchal hump that grows with age. Overall it is a drab olive green with some hints of brown, black, blue and gray coloring. They have special characteristics, adaptations to the fast moving streams of their natural habitat. Their lower fins act as struts for support and their swim bladder has been greatly reduced, which keeps them from readily floating. They don't hover, but rather 'jerk' or 'hop' from rock to rock. 

   All cichlids share a common feature that some saltwater fish such as wrasses and parrotfish have and that is a well-developed pharyngeal set of teeth that are in the throat, along with their regular teeth. Cichlids have spiny rays in the back parts of the anal, dorsal, pectoral, and pelvic fins to help discourage predators. The front part of these fins are soft and perfect for precise positions and effortless movements in the water as opposed to fast swimming.

   Cichlids have one nostril on each side while other fish have 2 sets. To sense "smells" in the water, they suck water in and expel the water right back out after being "sampled" for a short or longer time, depending on how much the cichlid needs to "smell" the water. This feature is shared by saltwater damselfish and cichlids are thought to be closely related.

The Lionhead Cichlid is an omnivore that can be fed live foods, frozen and prepared foods, algae, flake and pelleted foods. Feed 2 to 3 times a day in smaller amounts instead of a large quantity once a day. This will keep the water quality higher over a longer time. All fish benefit from vitamins and supplements added to their foods.

   A minimum of 30 gallons is suggested. They like vigorous water movement along with strong efficient filtration. They need a lot of caves near the bottom of the tank for retreating, providing several places at varying intervals works well. They do not bother plants, which is great for those who like their aquascaping. Provide plants that are hardy and individually potted. They are not demanding about the pH and hardness but very clean. oxygen rich water is important. Do water changes of 30% to 50% weekly, depending on stocking numbers. 

   They are subject to infections as well as other diseases that ail all freshwater fish, especially if water quality is ignored. One common problem is Ich. It can be treated with the elevation of the tank temperature to 86° F (30° C) for 3 days. Intestinal disease can be treated with metronidazol.

  This cichlid is considered to be a community fish with the right tank mates.They can be kept with other small peaceful fish that are not bottom dwellers. They do best in a species specific tank and can be kept as a pair, but will not get along with other conspecifics. They will often pair for life and remain solitary if their mate should die. Like other cichlids, they become more territorial during spawning.

The Lionhead Cichlid will form a patriarchal/matriarchal family and are very good parents. They will often pair for life, forgoing a new partner if their mate dies. Get a group of juveniles and let them pair up, then remove the others or they will be attacked. They will become sexually mature at 2 to 3 inches.

   They are a substrate spawner that prefers the security of a cave. The pair will dig a den together underneath a rock and spawn. The female will lay between 20 and 60 eggs, and never more than 150. The female will stick the eggs to the roof of their den. After a week the eggs will hatch and the fry will be swimming 7 days later. The parents will guard their fry until the next brood. They will lead their young out into the open water of the tank to feed, and the parents will masticate food for the fry if the food is too large. They are really excellent parents.
