Tiny ocean creatures known as sea sapphires perform a sort of magic trick as they swim: One second they appear in splendid iridescent shades of blue, purple or green, and the next they may turn invisible (at least the blue ones turn completely transparent). How do they get their bright colors and what enables them to “disappear?” New research at the Weizmann Institute has solved the mystery of these colorful, vanishing creatures, which are known scientifically as Sapphirinidae. The findings, which recently appeared in the Journal of the American Chemical Society, could inspire the development of new optical technologies.

Available in the UK only sporadically, and usually costing up to around £500 for a good specimen, Pelicier’s Perchlet Plectranthias pelicieri could easily be mistaken for a Hawkfish if one judges it solely on its general demeanour. This species is actually an Anthias though, and grows to a maximum size of around 5cm. A deepwater species, it is relatively hardy but can also be quite shy. This species should only be kept in a completely covered tank with other peaceful fishes and take note that it may consume passive ornamental inverts such as small shrimps and molluscs, and even fishes significantly smaller than itself.

We were also curious to experience the ‘direct sale’ acquisition of a skimmer via the ‘factory to end user’ pathway used by this supplier. Continue reading Review: Coral Box Cloud 9 DC Skimmer→
