Corals go through cycles of colour changes when something in the condition of your tank water changes. If you really want to get optimum colour, you have to go for optimum parameters... and all this is also experiementation. A frag of the same coral in two different tanks may grow differently and have different colours. Genetically, not all coral specimens are the same... you can't expect a certain colour if its of a different colour morph.

Warming of the sea surface by as little as several tenths of a degree can pose a serious threat to King penguins. A unique system allowed researchers tracked more than 450 individual King penguins over nine years in their natural environment, within the Crozet Archipelago. View the full article

Most times, its not just about the intensity or photoperiod, it could also be factors like waterflow or water quality. If there are other stress factors like parasites or predators, the coral may also change colour. The white tips look like growth tips.

It's good news that he has a good appetite, it means his chances of survival is strong. He does look a little thin though. It could be cyanide poisoning? Just speculating.

His phone number came up in a search on his nick. I strongly urge buyers to exercise caution buying from anyone with a new nick as there are known people with zero morals who take advantage of this forum to sell things only.

Looks like a very sick yellow tang that is super-faded.

Beckett = pure power, so powerful, its scary....

Hahaha... the Ken Lee tulibu dibu douchoo..... !!!!!

The flowrate in the main tank can be very high.... you can put in like 20 Tunze streams + seaswirls + wavebox to create a crazy whirlpool but if your tunrover over from main tank to sump is very low (where your mechanical filtration is eg skimmer), its extremely pointless. It's like a public toilet or smoking lounge with a very tiny hole for ventilation.... how do you expect the smell to escape and fresh air to be come in?

Researchers are investigating a radical new design for cargo ships that would eliminate ballast tanks, the water-filled compartments that enable non-native creatures to sneak into the Great Lakes from overseas. View the full article

Scientists have made the first global-scale analysis of the processes leading to freshwater fish invasion in river basins. This phenomenon affects most river ecosystems of countries of the Northern hemisphere. However, in the context of economic growth developing countries are now experiencing, their river basins, home to the greater part of freshwater fish biodiversity, are at risk of the same fate unless vigilance is applied.

The beaches of French Guiana constitute a major reproduction site for leatherback turtles. This sea turtle, although a protected species, is threatened by human activity. Female turtles return to the same beach every two to three years to lay their eggs; what happens in the interval remains a mystery. In a new study a group of French and Belgian scientists found that the turtles segregate into two distinct feeding units. View the full article

A new study predicts that climate change will irreversibly alter water circulation in Lake Tahoe in the Western US, radically changing the conditions for plants and fish in the lake -- and it could happen in 10 years. View the full article

oops. I changed back the forum to show all posts, now just the last 30 days! Sorry!

Over two hundred million humans depend for their subsistence on the fact that coral has an addiction to "junk food" -- and orders its partners, the symbiotic algae, to make it. This curious arrangement is one of nature's most delicate and complex partnerships -- a collaboration now facing grave threats from climate change. View the full article

Ten Short-tailed Albatross chicks have been moved by helicopter, from their current stronghold on Torishima Island to the site of a former colony 350 km to the South-east. The potential for future volcanic events on Torishima is among the most serious threats to this vulnerable species. Currently, 80-85% of the world population breeds on a highly erodible slope on the outwash plain from the caldera of an active volcano. View the full article

One of the oldest and most complete plesiosaur fossils recovered in North America, and the oldest yet discovered from the Cretaceous Period, represents a new genus of the prehistoric aquatic predator according to palaeontologists who have formally described the creature after its remains were uncovered in a mine near Fort McMurray in 1994.

An MIT materials scientist's research on sea snails has helped transform battery technology and may end the era when cell phones die if they're dropped and PDAs must be replaced if they get dunked in the tub. Thanks to those sea snails and a eureka moment a professor of Materials Science and Engineering and Biological Engineering is developing smart nano-materials -- hybrids of organic and inorganic components -- beginning with a rechargeable, biologically based battery that looks like plastic food wrap.

With the number of terrestrial sources that yield novel treatments for human disease decreasing year by year, the oceans have been tapped as a promising resource for discovering new natural biomedicines. Two new studies each utilizing mass spectrometry in novel ways, have helped narrow the gap in identifying potent natural compounds from the sea that could one day treat diseases such as cancer.

While rabbits continue to ravage Australia's native landscapes, rabbit fish may help save large areas of the Great Barrier Reef from destruction. The reason, say scientists, is the same in both cases -- both rabbits and rabbit fish are efficient herbivores, capable of stripping an area of vegetation. However, in the case of the Reef, it is the vegetation that is the problem -- and the rabbit fish, the answer. View the full article

Scientists in the North Pacific have sighted a creature of great rarity and even myth: a white whale. The white killer whale was spotted with its pod about two miles off Kanaga Volcano, part of Alaska's Aleutian Islands, on February 23. At the time, the marine researchers were assessing pollock fish stocks near Steller sea lion haulout sites. View the full article

Scientists have revealed what may well be the first pervasive 'rule' of evolution. Researchers have found evidence which suggests that evolution drives animals to become increasingly more complex. View the full article
