Common goldfish are often fed to big predatory fish, who dispatch their prey quickly in the confines of an aquarium. Yet, one goldfish managed to escape the jaws of death and survive undetected for at least seven years, secretly growing to 10 inches (25cm) in length!
Starfish that reproduce through cloning avoid ageing to a greater extent than those that propagate through sexual reproduction. This is shown by a new research study in which researchers from the University of Gothenburg participated. The study has recently been published in the journal 'Heredity.'
Turns out, just about every marine animal at every step of the food chain is ... and at alarming rates. Earlier in the year, researchers confirmed that corals were eating microplastics.. Now new research provides indisputable evidence that zooplankton are eating lots of microplastics in the wild, which means every animal up the food chain is as well. Crikey!
We love seeing aquariums of yesteryear. Two more antique aquariums listed on eBay - a 1876 cast iron tank and a seahorse-legged aquarium/stand setup - provide us a glimpse into our fishkeeping past.
This is a cast iron framed aquarium manufactured by JW Fiske Ironworks in 1876 (nearly 140 years old!). It measures 36x15x15 inches. Aside from the super heavy and intricate iron frame and base, the aquarium also features mirrors inlayed into the four inside corners of the aquarium.
Fiske was based in New York City and was America's most prominent iron and zincwork manufacturer in the 19th century. Their metalworks include a variety of aquariums ranging from this "table-top" aquarium to complete stand+frame+aquarium systems.
Here is a slightly younger aquarium system circa 1920s-1930s which features beautiful seahorse legs. This aquarium/stand was manufactured by the Jewel Aquarium Company of Chicago, IL (USA). Unlike JW Fiske whose metalworks spanned many different industries, Jewel specialized in only high-end elaborate iron aquarium stands such as this seahorse design, which the company was most recognized for. The seahorse legs were each hand hammered then coated with bronze with patina. Even if its aesthetics don't fit modern tastes, its craftsmanship is impressive and rarely (if ever) seen these days.
We share another beautiful image by Mitchell Brown. Corals under fluorescence are breathtaking sights to behold. Zoanthids are coveted for their flower-like beauty, but they are truly special when fluorescing!
Beautiful captive-bred Madagascar clownfish are finally available in the marine aquarium hobby! From consistently eating their own eggs to now laying batches one on top of the other, the broodstock pair has come full circle in their spawning behavior.
A new fascinating study discovered that giant clams (Tridacna squamosa) were much better able to survive and grow in elevated CO2 waters when they are under high PAR lighting.
This short video by Erik Woolcott shows the fascinating movements of a gorgonian and a leather coral that can only be appreciated in time lapse. We love the ethereal lighting and Erik's good humor too!
All Top Fin plastic heaters (50W, 100W, 150W, 200W, and 250W) are potential shock hazards and should be immediately returned to Petsmart for a full refund. This recall applies only to Top Fin's all plastic (not glass) heaters.
Researchers are learning about how mantis shrimps can neutralize shock waves (e.g. from their famous pummeling attacks) by filtering out specific frequencies. This discovery is inspiring new helmet and armor design. We're beginning to believe that eventually every design is going to be inspired by mantis shrimp.
A new study discovered that the gills of developing clownfish were severely damaged when fish were exposed to sediment levels simulating conditions found on some inshore reefs on the GBR. While further study is required to understand how sediment affects gills of adult reef fish, this finding has immediate implication for captive breeding.
Marine Aquarium Society of North America is currently holding its 2015 membership drive. The drive is sponsored by Tunze; new members will have a chance to win a Tunze Osmolator 3155. Plus $5 of each new renewal also goes towards Gary Meadows Reef Fund.
We revisit a spectacular coral reef from the Danish capital city of Copenhagen (Istedgade St. to be exact). The aquarium has matured beautifully over the past year into truly world-class living art.
Last year, we shared two videos of Istedgade Reef. Kenneth Olson has uploaded a new video of Istedgade Reef, and it's looking more gorgeous than ever! The reef tank features a wonderful balance of SPS, LPS, gorgonian, and soft corals cohabiting a sprawling aquascape in harmony.
Reef-A-Palooza, billed as America's largest marine aquarium show, began in Southern California but has since expanded to include shows in Florida and now New York. June 27 & 28 will be the Big Apple's first RAP.
A hobbyist decided to record the microscopic life swimming in a drop of reef aquarium water (now that's our type of reefkeeper!). The footage does not disappoint. Captive seawater is teeming with life. The next time you accidentally get tank water in your mouth, think about this video. You're welcome.
