For many, 2016 was a year best left forgotten, but it was actually a great year for scientists (and fishkeepers) thanks to the discovery of three new marine species. In the warm waters of Indonesia’s coral reefs, scientists formally described three new species of flasher wrasse - a stunningly vibrant fish that looks more at home in the neon strips of Las Vegas than in the seas of Bali.
The flasher is aptly named not just because of the eye-popping colour that makes it greatly prized amongst marine aquarists, but also because of its courtship behaviour. When the males are actively trying to attract the attentions of a willing female, they will quickly and dramatically intensify their colouration from relatively muted shades to firework bursts of vivid neon.
This powerful “flash” of colour is further enhanced by bouts of rapid, darting “dancing”, interspersed with moments of stillness during which the male spreads its dorsal and anal fins for extra attention. The overall effect is a display that’s definitely dazzling, and it’s perhaps the only time when male flashing is desirable.

Old favourites tend to be in the hobby for a long time with good reason, usually, it’s because they combine a lot of desirable traits. The metallic form of the Gold barb (Barbodes semifasciolatus) makes an excellent aquarium fish suitable for both tropical and temperate (unheated) setups. These young fishes at our Pyle store are a perfect beginner’s choice.
It’s that time of year when the heating goes back on, and this is something that many of us have in common with our pets. To ensure they remain healthy, it’s important to know that your aquarium heater is working properly and is set to the right temperature for the fishes you keep.
