species.
HAB
: Australia; Eastern Queensland and the Cape York Peninsula
S
: middle, top
TANK
: A tank measuring 24" (61 cm) with a capacity from 10-20 gallons (38-76 L) is recommended. Plant the tank along the edges and leave open swimming areas. The filter should create moderate circulation. Use a dark, fine gravel.
WATER
: pH 6.5-7.5 (7.0), 10-15 dH (12), 73-82°F (23-28°C)
SB
: An active, schooling species that can be combined with other gentle fish. This fish should be kept in groups of five or more.
SC
:
Corydoras,
Loricarids, tetras, hatchetfish, dwarf Rainbowfish
FOOD
: Live;
insect larvae
, crustaceans, worms, insects; flakes
SEX
: Males are more colorful and slightly larger.
B
: Follow suggestions for
M. splendida australis.
Use water values within the mentioned perimeters. The eggs are not molested by the parents and hatch after 12-16 days.
BP
: 5. An easily bred species.
R
: Make frequent partial water changes.
DC
: 5. The species is sensitive to unfavorable water conditions.

Telmatherina ladigesi
SYN
: None
PD
: The Celebes Rainbowfish has a slender, elongated body with lateral compression. There are two dorsal fins, the first being very small. The first rays of the second dorsal fin and anal fin develop into long,thread-like appendages. Males are yellow-brown in color with blue-green iridescence. An iridescent blue to green stripe extends laterally from the caudal fin to the gill cover. The first dorsal fin is amber colored while the other fins are yellowish. The first rays of the second dorsal and anal fins are black. The edges of the caudal fin are yellow with white ends. The rest of the fin is black. The colors of females are subdued and their fins are shorter.
SIZE
: To 3" (7.5 cm)
SS
: None
HAB
:
Indonesia
; in slow-moving water in the foothills of Sulawesi (Celebes), an island located west of Borneo and east of New Guinea
S
: middle
TANK
: 28" (70 cm) or 20-25 gallons (75 L). The tank should have densely planted areas, but also have open swimming areas. Provide a partial cover of floating plants to subdue the overhead lighting. The tank should be in a location to receive morning sun. Use a fine gravel substrate. The water should be well-aerated.
WATER
: pH 7-8 (7.1), 10-25 dH (14), 70-81°F (21-27°C). A 1% addition of salt is recommended. This can be accomplished by adding 7.5 TSP of salt/ 10 gallons (10 g/10 L)
SB
: A peaceful, schooling fish recommended for community tanks with fish that can tolerate brackish water. Keep this lively fish in groups of five or more.
SC
: Glass fish, Livebearers, Halfbeaks, Bumblebee fish
FOOD
: Prefers floating foods. Flakes; small pellets; live; aquatic and terrestrial insects, brine shrimp,
insect larvae
,
Tubifex
SEX
: Males have larger, more elaborate fins and better coloration.
B
: Use cool water with a temperature of 70-73°F (21-23°C). After courtship, the pair will spawn among plant leaves. Spawning takes place of a number of days to a number of weeks. The first batch of eggs are laid among the plants and number 30-50. The successive batches are laid with fewer eggs. After each laying, the eggs should be removed as the pair will consume them. The eggs hatch in 10-14 days. Raise the fry on crushed flake food and small live foods. The fry hang just below the water surface. They grow very slowly, but reach maturity at 7 months.
BP
: 7. Breeding the Celebes Rainbowfish is moderately difficult.
R
: This fish is very sensitive to changes in water properties. When adding the Celebes Rainbowfish to a tank, always allow adequate transfer acclimation time. Wild-caught specimen are very delicate and often live for only a short time. This fish needs frequent partial water changes to prosper.
DC
: 6. The Celebes Rainbowfish is sensitive to water conditions.

Using fish as livestock feed threatens global fisheries
(11/18/2009)
Fish doesn't just feed humans. Millions of tons of fish are fed every year to chickens, pigs, and even farmed fish even in the midst of rising concerns over fish stocks collapses around the world. Finding an alternative to fish as livestock feed would go a long way toward preventing the collapse of fish populations worldwide according to a new paper in Oryx.
ICCAT fails to protect critically endangered tuna—again
(11/15/2009)
The International Commissions for the Conservation of Atlantic Tuna (ICCAT) ignored the advice of its scientists to end fishing of the Atlantic bluefin tuna. Instead ICAAT set a quota of 13,500 tons of fish. This is not the first time ICCAT has flouted its own researchers' advice: it has repeatedly set quotas well-above its researchers' recommendations.
Governments, public failing to save world's species
(11/04/2009)
According to the International Union for the Conservation of Nature's (IUCN) 2008 report, released yesterday, 36 percent of the total species evaluated by the organization are threatened with extinction. If one adds the species classified as Near Threatened, the percentage jumps to 44 percent—nearly half.
Atlantic bluefin tuna should be banned internationally: ICCAT scientists
(10/29/2009)
Scientists with the International Commission for the Conservation of Atlantic Tuna (ICCAT) have said in a new report that a global ban on Atlantic bluefin tuna fishing is justified. ICCAT meets in November to decide if they will follow their scientist's recommendations.
The Yangtze River may have lost another inhabitant: the Chinese paddlefish
(10/22/2009)
In December of 2006 it was announced that the Yangtze River dolphin, commonly known as the baiji, had succumbed to extinction. The dolphin had survived on earth for 20 million years, but the species couldn't survive the combined onslaught of pollution, habitat loss, boat traffic, entanglement in fishing hooks, death from illegal electric fishing, and the construction of several massive dams. Now, another flagship species of the Yangtze River appears to have vanished.
Freshwater species worse off than land or marine
(10/15/2009)
Scientists have announced that freshwater species are likely the most threatened on earth. Extinction rates for freshwater inhabitants are currently four to six times the rates for terrestrial and marine species. Yet, these figures have not lead to action on the ground.
