Click through to see the images. Color Elements is a new product line from Fauna Marin (an Advanced Aquarist sponsor). According to Fauna Marin, Coral Elements are a "novel mix of growth and color enhancing trace elements, based on a unique and experimentally confirmed recipe, which perfectly adopts to modern artifical seasalt mixes. Developed by leading scientists, this state- of-the-art element mix aligns the micronutrient consumption of tropical corals with the environmental light conditions generated by LED lighting systems. It allows for stable conditions in the micronutrient budget in coral reef aquaria, and thereby significantly increases coral growth rates and coral coloration. Due to the special formulation of the elements this mix does not lead to the accumulation of excess toxic trace metals in the aquarium and effectively prevents the growth of unwanted algae." Fauna Marin currently has three Color Elements that they are offering: Red Purple Complex Green Blue Complex Blue Purple Complex Each of these products are reported to increase calcification rates, coral tissue growth, coloration in SPS and LPS corals even under lower lighting conditions, improve their fluorescence, and help harden them against radiation stress. They can be dosed either by hand or using a 3-way doser and are compatible with the Balling Light System, Zeolith System, or pellet-based systems. An example of a coral grown with Color Elements. While the website does not list exactly what each product will do nor what they contain, inferring from the labeling each product will help promote a given color range in your corals. The manufacturer states that each product is based on marine organic compounds and trace elements and that you can see a difference in your corals after the first dose. We would like to hear more details as to what the products contain. Fauna Marin has a photo gallery of corals reportedly grown using the new Color Elements and you can see them on their Facebook page. Color Elements will replace Fauna Marin's PowerTrace Elements as they cost less and are more effective. Color Elements are available in both 250mL and 500mL bottles and retail in Europe for approximately $18 and $25 respectively. Fauna Marin states that the products will show up in the United States within the next couple months. View the full article

You can dont feed your SPS if you have fishes inside your tank since in certain extent waste products from your fish is a food source for your corals. The main source of SPS growth come from lighting, however feeding the SPS corals will give you better extent growth and coloration.

All hermit crabs appropriate abandoned snail shells for their homes, but the dozen or so species of land-based hermit crabs – popular terrarium pets – are the only ones that hollow out and remodel their shells, sometimes doubling the internal volume. This provides more room to grow, more room for eggs – sometimes a thousand more eggs – and a lighter home to lug around as they forage. But empty snail shells are rare on land, so the best hope of moving to a new home is to kick others out of their remodeled shells, said Mark Laidre, a UC Berkeley Miller Post-Doctoral Fellow who reported this unusual behavior in this month’s issue of the journal Current Biology. When three or more terrestrial hermit crabs congregate, they quickly attract dozens of others eager to trade up. They typically form a conga line, smallest to largest, each holding onto the crab in front of it, and, once a hapless crab is wrenched from its shell, simultaneously move into larger shells. A free-for-all takes place whenever three or more hermit crabs congregate, with all crabs intent on displacing someone else to get a larger shell. “The one that gets yanked out of its shell is often left with the smallest shell, which it can’t really protect itself with,” said Laidre, who is in the Department of Integrative Biology. “Then it’s liable to be eaten by anything. For hermit crabs, it’s really their sociality that drives predation.” Laidre says the crabs’ unusual behavior is a rare example of how evolving to take advantage of a specialized niche – in this case, land versus ocean – led to an unexpected byproduct: socialization in a typically solitary animal. “No matter how exactly the hermit tenants modify their shellters, they exemplify an important, if obvious, evolutionary truth: living things have been altering and remodeling their surroundings throughout the history of life,” wrote UC Davis evolutionary biologist Geerat J. Vermeij in a commentary in the same journal. For decades, Vermeij has studied how animals’ behavior affects their own evolution – what biologists term “niche construction” – as opposed to the well-known Darwinian idea that the environment affects evolution through natural selection. “Organisms are not just passive pawns subjected to the selective whims of enemies and allies, but active participants in creating and modifying their internal as well as their external conditions of life,” Vermeij concluded. A marine snail shell newly vacated by its gastropod owner (left) and a shell that has been remodeled by a hermit crab. Laidre conducted his studies on the Pacific shore of Costa Rica, where the hermit crab Coenobita compressus can be found by the millions along tropical beaches. He tethered individual crabs, the largest about three inches long, to a post and monitored the free-for-all that typically appeared within 10-15 minutes. Most of the 800 or so species of hermit crab live in the ocean, where empty snail shells are common because of the prevalence of predators like shell-crushing crabs with wrench-like pincers, snail-eating puffer fish and stomatopods, which have the fastest and most destructive punch of any predator. On land, however, the only shells available come from marine snails tossed ashore by waves. Their rarity and the fact that few land predators can break open these shells to get at the hermit crab may have led the crabs to remodel the shells to make them lighter and more spacious, Laidre said. The importance of remodeled shells became evident after an experiment in which he pulled crabs from their homes and instead offered them newly vacated snail shells. None survived. Apparently, he said, only the smallest hermit crabs take advantage of new shells, since only the small hermit crabs can fit inside the unremodeled shells. Even if a crab can fit inside the shell, it still must expend time and energy to hollow it out, and this is something hermit crabs of all sizes would prefer to avoid if possible. The work was funded by UC Berkeley’s Miller Institute. (Press Release UC Berkeley) View the full article

DId you see any mantis shrimp? Sent from my GT-I9300 using Tapatalk 2

From the look of the photo I have already guess it is done by reef systems. That's a lot of salt you are getting lol..

Yes, it should start to heal slowly,,

Last Emperor already sold in fish channel. Still have a male personifer , scribber, nice blue face, earspot angel,flame hawk, helfirichi pair at a very good price.

Coral farm still have some golden butterfly, purple tang, small size ear spot angel, emperor ect..

For dry goods with good variety , you can check out Madpetz under our sponsor section.

Very interesting concept on the diy reactor, maybe you can share with us more how's it is make? You can also consider using clear pvc at the center section which allow you to view and see if the pallet is trumbling or not. Sent from my GT-I9300 using Tapatalk 2

Click through to see the images. Scientists at the Georgia Institute of Technology have found evidence that these "mutualistic" fish respond to chemical signals from the coral like a 911 emergency call -- in a matter of minutes. The inch-long fish -- known as gobies -- spend their entire lives in the crevices of specific corals, receiving protection from their own predators while removing threats to the corals. This symbiotic relationship between the fish and the coral on which they live is the first known example of one species chemically signaling a consumer species to remove competitors. It is similar to the symbiotic relationship between Acacia trees and mutualist ants in which the ants receive food and shelter while protecting the trees from both competitors and consumers. "This species of coral is recruiting inch-long bodyguards," said Mark Hay, a professor in the School of Biology at Georgia Tech. "There is a careful and nuanced dance of the odors that makes all this happen. The fish have evolved to cue on the odor released into the water by the coral, and they very quickly take care of the problem." The research, supported the National Science Foundation, the National Institutes of Health and the Teasley Endowment at Georgia Tech, was reported November 8 in the journal Science. The research was done as part of a long-term study of chemical signaling on Fiji Island coral reefs aimed at understanding these threatened ecosystems and discovering chemicals that may be useful as pharmaceuticals. Because they control the growth of seaweeds that damage coral, the importance of large herbivorous fish to maintaining the health of coral reefs has been known for some time. But Georgia Tech postdoctoral fellow Danielle Dixson suspected that the role of the gobies might be more complicated. To study that relationship, she and Hay set up a series of experiments to observe how the fish would respond when the coral that shelters them was threatened. They studied Acropora nasuta, a species in a genus of coral important to reef ecosystems because it grows rapidly and provides much of the structure for reefs. To threaten the coral, the researchers moved filaments of Chlorodesmis fastigiata, a species of seaweed that is particularly chemically toxic to corals, into contact with the coral. Within a few minutes of the seaweed contacting the coral, two species of gobies -- Gobidon histrio and Paragobidon enchinocephalus -- moved toward the site of contact and began neatly trimming away the offending seaweed. "These little fish would come out and mow the seaweed off so it didn't touch the coral," said Hay, who holds the Harry and Linda Teasley Chair in Environmental Biology at Georgia Tech. "This takes place very rapidly, which means it must be very important to both the coral and the fish. The coral releases a chemical and the fish respond right away." In corals occupied by the gobies, the amount of offending seaweed declined 30 percent over a three-day period, and the amount of damage to the coral declined by 70 to 80 percent. Control corals that had no gobies living with them had no change in the amount of toxic seaweed and were badly damaged by the seaweed. To determine what was attracting the fish, Dixson and Hay collected samples of water from locations (1) near the seaweed by itself, (2) where the seaweed was contacting the coral, and (3) from coral that had been in contact with the seaweed -- 20 minutes after the seaweed had been removed. They released the samples near other corals that hosted gobies, which were attracted to the samples taken from the seaweed-coral contact area and the damaged coral -- but not the seaweed by itself. "We demonstrated that the coral is emitting some signal or cue that attracts the fish to remove the encroaching seaweed," Hay said. "The fish are not responding to the seaweed itself." Similar waters collected from a different species of coral placed in contact with the seaweed did not attract the fish, suggesting they were only interested in removing seaweed from their host coral. Finally, the researchers obtained the chemical extract of the toxic seaweed and placed it onto nylon filaments designed to stimulate the mechanical effects of seaweed. They also created simulated seaweed samples without the toxic extract. When placed in contact with the coral, the fish were attracted to areas in which the chemical-containing mimic contacted the coral, but not to the area contacting the mimic without the chemical. By studying the contents of the fish digestive systems, the researchers learned that one species -- Gobidon histrio -- actually eats the noxious seaweed, while the other fish apparently bites it off without eating it. In the former, consuming the toxic seaweed makes the fish less attractive to predators. The two species of fish also eat mucus from the coral, as well as algae from the coral base and zooplankton from the water column. By defending the corals, the gobies are thus defending the home in which they shelter and feed. "The fish are getting protection in a safe place to live and food from the coral," Hay noted. "The coral gets a bodyguard in exchange for a small amount of food. It's kind of like paying taxes in exchange for police protection." As a next step, Hay and Dixson would like to determine if other species of coral and fish have similar symbiotic relationships. And they'd like to understand more about how the chemical signaling and symbiotic relationship came into being. "These kinds of positive interactions needs to be better understood because they tell us something about the pressures that have gone on through time on these corals," said Hay. "If they have evolved to signal these gobies when a competitor shows up, then competition has been important throughout evolutionary time." Journal Reference: D. L. Dixson, M. E. Hay. Corals Chemically Cue Mutualistic Fishes to Remove Competing Seaweeds.

Anyone spotted jelly fish at farm this week ?

Click through to see the images. A pughead skeletal deformity is where the entire top jaw is compressed downward, which ends up making the bottom jaw look like it is pushed outward. While pughead skeletal deformities are more common in captive fish, this condition is relatively rare in wild fish. In captive populations, this condition is typically attributed to "chemical contaminants, dietary limitations or excesses, temperature variations during larval development, and inbreeding." According to Francini-Filho and Amado-Filho, the two scientists who reported this abnormality in the journal Coral Reefs, this is the first recorded incident of pughead skeletal deformity reported in Queen Angelfish and in the family Pomacanthidae. During a diving trip between May 24 and June 8, 2011, they found two Queen Angelfish, Holacanthus ciliaris, while at St. Peter and St. Paul Archipelago, Mid Atlantic Ridge, Brazil. Both fish were large, ranging from 30 to 35 cm in length (12-14 inches) and appeared healthy with the exception of the pughead skeletal deformity. Given that inbreeding and low genetic connectivity are already reported for this species in St. Peter and St. Paul Archipelago, Francini-Filho and Amado-Filho both believe this is what caused the abnormality.
