Product Review: Products for 'Rapid Cycling' of Marine Aquaria: Brightwell Aquatics' MicroBacter7 and Continuum Aquatics' BacterGen.M
Two products were tested under controlled conditions for their abilities to consume/convert carbon and nitrogen-based compounds (referred to as "cycling" by many hobbyists.) Results suggest that, at dosages recommended by the manufacturers, these products contain sufficient numbers of carbon-cycling bacteria to properly inoculate biochemical oxygen demand tests, and ammonia-oxidizing bacteria are present in numbers that can "seed" a sterile environment, and perhaps hasten the aerobic portion of the nitrogen cycle along by a few days when used as a supplement to conventional seeding via live rock, live sand, and hardy "starter" fishes. Potential problems with over-dosing are also discussed.
A plant-less, coral-less aquarium isn't what we usually write about, but this unique build is a remarkable engineering achievement. And considering where it's located, it's probably a good idea it isn't filled with fussy livestock.
We've written about underwater "waterfalls" before, but this planted aquarium takes the concept up a notch. This 3 foot aquascape features not one but two full-height underwater "waterfalls."
Pachyseris inattesa is the newest described species of 'elephant skin' coral. This new species has a smoother appearance than its congeners aquarists sometimes encounter. The best we can describe P.inattesa is a cross between Montipora verrucosa and Leptoseris sp. corals. (It's a good thing we have pictures!)
Benzodiazepine is a class of drugs commonly used to treat anxiety and sleep disorders in humans. But research is finding that this type of drug has a surprising effect on fish. It decreases the mortality of fish fry, makes fish bolder and more active, and feed with more vigor. Is psychoactive medication the next frontier for aquarists and breeders?
For $6500 USD (OBO), you can own a piece of aquarium history. This 31 gallon antique aquarium features amenities you will never see in any modern aquarium such as back-lit stained glass, beveled glass details, iron stand and frame, and marble base. They sure don't make them like they used to.
Let's all welcome the first Madagascar Clownfish baby born in captivity! Breeding a rare species of clownfish has been a goal of mine for many years, and it seems fitting that after 7 batches and thousands of eggs I was able to achieve this with an ‘N’ of one!
Remember the days when Discovery channel produced educational programming? This year's Shark Week has proven the network has completely abandoned quality content to pander for ratings. To think: Advanced Aquarist once promoted Shark Week.
Texas-based Fritz Aquatics has reached an agreement with Sergeants Pet Care Products to both manufacture and distribute the popular Mardel chemical/pharmaceutical brand (a product line that includes Maracyn and CopperSafe, which most aquarists have used). Fritz provides Advanced Aquarist with their press release.
This isn't exactly breaking news, but no aquarist publication AFAWK reported about these two Corydoras spp. described earlier this year. And we know how much freshwater aquarists adore cories.
Dr. Jafarey, staff veterinarian at the Toledo Zoo, answers why an aquarist may experience massive fish die-off with symptoms of swollen eyes and abnormal buoyancy.
The orange-spotted filefish/harlequin filefish is one of the most beautiful, weirdly shaped and colorful reef fish available to marine aquarists. Once thought of as strict coral-eaters, bold reefkeepers have attempted this species in reef tanks with mostly positive experiences. A new research may explain why.
I'm sure this thought has crossed many reefkeepers' minds who live close to the ocean: How cool would it be to have a tropical reef nearby? Careful what we wish for. Many studies show coral reefs and their fish are moving poleward. A new study shows tropical fish are making quick work of temperate kelp forests.
Scientists studying fishes' response to warming water temperatures discovered tropical fish may have the toughest time coping. Tropical wrasses had the narrowest thermal range and able to only tolerate a few degrees of temperature shift before heart failure.
There's just something magically calming and therapeutic about planted aquariums. Lose yourself (if only for two minutes) in this ADA 90 (50 US gallon) aquascape by "Raw Aquatic Design." We just wish the video was longer ... like 2 hours longer. Serenity now.
