livingstonii is another shell-dwelling mbuna.
Habitat: Eastern Africa; inhabits empty snail shells (
Lanistes) of sandy regions of Lake Malawi
S: bottom, middle
Aquarium: 30" (76 cm) or 20-30 gallons (75-114 L).
The tank should have a rocky set-up
with caves and overhangs.
Provide several large snails shells for each fish.
Leave open swimming areas and use coral
sand substrate.
Use a strong light to promote the growth of algae.
Water chemistry: pH 7.5-8.8 (8.2), 12-22 dH (16), 73-79°F (23-26°C)
Social behavior: A territorial species that will guard its snail shell against intruders.
This
species will not usually harm plants and is unaggressive towards other species.
Suggested companions: Lake Tanganyika Rainbowfish, mbunas,
Synodontis
FOOD: Algae; flake; live; snails, bloodworms, mosquito larvae, microorganisms, crustaceans,
snails, Tubifex
; chopped meat; pellets; tablets; vegetables; peas, lettuce, spinach; fruit.
Sexual differences: Males have brighter egg-spots on their anal fin.
Breeding techniques: Use water with a pH around 8.2 with a water temperature from 79-82°F (26-28°C).
Keep
at least three females with the male.
The female is an ovophile mouth brooder who lays as many as 60 eggs,
which she incubates for three weeks.
She continues to guard the fry for a week after they emerge from the
mouth.
Start feeding with Artemia
and crushed flake foods.
Breeding potential: 5.
An easily bred species.
Remarks: Will seek shelter in snail shells when danger is present.
Difficulty of care: 4.
This relatively peaceful mbuna is an excellent choice for a mbuna community tank.

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.
