On June 8, 2010 an unassuming patent was issued to Dennis Fredricks for a “Curvilinear Aquarium Light”. The claim in the patent is for an “ornamental design for a curvilinear aquarium light, as shown and described.” The idea is simple, but potentially extremely helpful when performing tank maintenance. The light is described as an “aquarium light [...]
Some of my favorite fish are nearly impossible to keep. Specifically I’m talking about Meyer’s Butterflyfish (Chaetodon meyeri), the Ornate Butterflyfish (Chaetodon ornatissimus) and the Reticulated Butterflyfish (Chaetodon reticulatus). Some ichthyologists place these obligated coral feeders (corallivores) within the Citharoedus subgenus. All three share similar osteology and a jaw structure that allows them to prey on [...]
Singapore’s reefing scene is abuzz over two juvenile specimens that will make you say Awww and your wallet say Oh! Shown up top is a pint sized Juvenile Wrought Iron Butterflyfish (Chaetodon daedalma). C. daedalma in sub 3″ sizes has become increasingly rare over the last couple years with a recent batch selling in Japan [...]
Kalk, lemon juice, hydrogen peroxide, trace element concoctions, even lye; most of these have some efficacy against Aiptasia or pest Majano Anemones, but odds are you’ve never tried to electrocute them. Yes, we’re for real. Joseph’s brew may be put to the bench in favor of something a bit more powerful. Paul Baldassano’s innovative gadget [...]
In a recent study published in Animal Cognition, scientists from Kyoto University have documented remarkable spatial memory (remembering their surroundings and environment) in the migratory marine cardinalfish Apogon notatus. During each breeding season female A. notatus establish their small territory nearby the seafloor where she will spawn with males. During an extended study scientists found that in [...]
Turbinaria reniformis is a hardy, popular and beautiful coral species that adapts quite well to the home aquarium. Most aquarists, however, are not familiar with one of its relatives, Turbinaria heronensis. Colonies of T. heronensis are like a caricature of T. reniformis, in that the coralites are much more prominent, tubular and irregular. Think of Samy [...]
