/ Africa / Lake Malawi / Big-lipped Cichlid
Big-lipped Cichlid, Euchilus
Cheilochromis euchilus | Pictures
Synonyms: Cyrtocara
euchila, Haplochromis euchilus
Physical description: An elongated cichlid, whose head is proportionally large when compared to the rest
of the body.
The lips are very large, as are the eyes.
The body color is light gold to beige.
The
belly is white.
Two brown-black stripes mark the body.
The first runs from the corner of the mouth,
through the eye, and extends to the fork of the caudal fin.
The second line runs from the top of the forehead,
back to the base of the caudal fin.
The fins are usually light brown with some light markings.
Size/Length: Males to 13" (33 cm), female to 10" (25 cm)
Similar species: None
Habitat: Eastern Africa; along the rocky coastline of Lake Malawi.
S: bottom, middle
Aquarium: 40" (101 cm) or 45-55 gallons (170-209 L) is sufficient for small fish under
5" (13 cm) in length.
Adult fish should be moved to an 72" (183 cm) or 100 gallon (378 L) tank.
Use
large, sturdy rocks structures to create caves and crevices.
Anchor the structure well-as this fish may burrow.
Large,
broad-leafed plants can be used.
Algae growth is welcomed.
Water chemistry: 7.5-8.8 (8.2), 10-25 dH (18), 75-82°F (24-28°C)
Social behavior: A large, but peaceful fish that likes to form schools.
The Big-lipped Cichlid will set-up territories
to defend.
Combine several females per each male.
Small fish (under 3" ) are likely to be mistaken for food.
Suggested companions: Lake Malawi Haplochromines,
Synodontis, larger mbunas,
Polypterus
FOOD: Algae; live;
Tubifex, crustaceans, insect larvae; large flakes;
tablets; pellets
Sexual differences: The male is larger with more intense colors.
Breeding techniques: Use a large tank with a pH from 8.0-8.5, a water hardness from 10-16 dH, and a water
temperature from 79-82°F (26-28°C).
Keep one male with three or four females.
The female will spawn 20-60 eggs (although
broods of 150 have been reported) on a rocky surface before taking them into her mouth.
The eggs are then fertilized by way
of the dummy-egg method.
The young released after 20-28 days.
The female continues brood care, taking the fry
into her mouth when danger approaches and at night.
Start feeding the young with
Artemia,
Cyclops, and powdered dry foods.
The
young are sexually mature at four to five inches (10-13 cm).
Breeding potential: 8.
A difficult fish to breed.
Remarks: The large lips that this cichlid possesses are a result of feeding specialization.
They
are used for rasping algae and animal life that can be found on rocks.
Difficulty of care: 6.
The Big-lipped cichlid is moderately difficult in care because of the large size that it
reaches and the tank that it eventually requires.

Piranhas originated when Amazon was flooded by seawater
(12/4/2007) South America's piranha family of fish -- notorious as eaters of flesh -- can be traced back to a single ancestor which dispersed when the Amazon was flooded by seawater some five million years ago, report researchers from the Institut de Recherche Pour le Developpement (IRD). Today piranhas are exclusively freshwater fish found from the Orinoco River basin in Venezuela to the Parana in Argentina.
How to save the world's oceans from overfishing
(7/8/2007) Global fishing stocks are in trouble. After expanding from 18 millions tons in 1950 to around 94 million tons in 2000, annual world fish catch has leveled off and may even be declining. Scientists estimate that the number of large predatory fish in the oceans has fallen by 90 percent since the 1950s, while about one-quarter of the world's fisheries are overexploited, depleted, or recovering from depletion. Despite these dire trends, the situation is changing. Today some of the world's largest environmental groups are focused on addressing the health of marine life and oceans, while sustainable fisheries management is at the top of the agenda for intergovenmental bodies. At the forefront of these efforts is Mike Sutton, director of the Monterey Bay Aquarium's conservation program: the Center for the Future of the Oceans. The aquarium, which has long been recognized as one of the world's most important marine research facilities, is pioneering new strategies for protecting the planet's oceans. Sutton says the approach has four parts: establishing new marine protected areas, pushing for ocean policy reform, promoting sustainable seafood, and protecting wildlife and marine ecosystems.
