No sooner than we wrap up our coverage of all of ORA’s 2014 captive bred fish and aquacultured frags, the famed fish breeders announce one more entry for the year. Yesterday, they revealed tha they had bred the Hector’s Goby (Koumansetta hectori), a nifty little fish that is as strikingly beautiful as it is peaceful. This tiny fish measures just 2″ long at its maximum size, and it spends a majority of the day hovering hear the rocks while grazing on various types of algae. Thought to be the first time this fish has ever been captive-bred, ORA had some difficulty getting this fish to market, so to speak. This was due in part to the fish’s extremely tiny size, unreliable spawning amongst broodstock individuals, relatively long larval stages, and overall fragile larvae. Thankfully, ORA’s experience with the Priolepis genus translated flawlessly to the Hector’s Goby and they were eventually able to overcome those barriers. by AquaNerd | Nov 11, 2014 | Equipment, Science
Last year, Pacific Sun debuted the smartest, fanciest dosing pump system on the planet in the Kore 5th, so it only makes sense that they develop accessories that will boost the effectiveness of that system. One of the major drawbacks to automated dosing is the fact that the bottles of chemicals sit in an aquarium stand, untouched and forgotten, allowing the critical components of the solutions to settle on the bottoms of the bottles. While the responsible hobbyist might come by and shake the bottles regularly, let’s face it, not all of us do that step. To answer that conundrum, Pacific Sun has released some teaser info on their Kore 5th Magnet Stirrer, which as its name suggests keeps the solutions at their freshest by keeping them mixed up prior to dosing. If the Magnetic Stirrer is anything like what we see in other applications, then the hobbyist will have to drop a magnetic stir bar into each bottle and place it on the rack to let it do its thing. The stir rates and times are all controlled through the actual Kore 5th dosing pump, which attaches to the top of the rack, as seen in the photos by AquaNerd | Oct 20, 2014 | Equipment, Fish, Science
