Picture of the Week, Sand Sifting Starfish
The focus of the latest AquaNerd Picture of the Week rests on a very popular aquarium invertebrate, the sand sifting starfish (Astropecten polycanthus). This particular starfish is such a fan favorite because it does a terrific job of agitating the top few inches of the sand bed, often consuming leftover fish food, detritus, and various [...]
Picture of the Week, Red Acanthastrea
Acanthastrea lordhowensis corals, or simply acans for short, have sort of fallen from their top spot in terms of desirability and trendiness over the last couple of years. But that trend hasn’t stopped us from featuring this gorgeous, and rather puffy, individual in the latest AquaNerd Picture of the Week. This coral is deep red [...]
Picture of the Week, Where’s Waldo the Coral Hitch Hiker
This week’s AquaNerd Picture of the Week is going to be slightly different. Instead of telling you all about the critter in the photo, we’re leaving it a mystery and letting you guess what it is. Inside the blue tipped Acropora colony resides a hitch hiker. It stays buried in the branch of the coral, [...]
Picture of the Week, Red and White Coco Worm
In this week’s AquaNerd Picture of the Week, we turn our attention to a beautiful and often underrated invertebrate, the Coco worm. These gorgeous tube worms excrete a hard, calcified tube, which they live in for protection. Their elaborate gills, seen in the image above, are obviously the worm’s most striking feature, as it isn’t [...]
Picture of the Week, Fathead Sunburst Anthias
Pictured in the latest AquaNerd Pic of the Week is a lone Fathead Sunburst Anthias (Serranocirrhitus latus) hanging out in a very cryptic and dim portion of a mixed reef aquarium. Unlike most anthias that school/shoal in small groups, the sunburst anthias actually does better alone or as a male/female pair, provided the aquarium is [...]
Overuse of Blue Lighting in Coral Sales
A couple of days ago, we posted an image of a rather astonishing dark blue plate coral that was being shown off by an online vendor. While the coral was unique in its own right, its colors were definitely being enhanced by intense actinic blue lighting. This enhancement was evident by glowing tentacles on the [...]
Picture of the Week, Rainbow Wellsophyllia
Pictured in this week’s AquaNerd Pic of the Week is a top down shot of an absolutely stunning rainbow colored Wellsophyllia brain coral, and it’s one that also has a sexy neighbor…another great Wellso. These open brain colors are the perfect match for the reef keeper looking to instantly add a healthy dose of color to their [...]
Picture of the Week, Rose Bubble Tip Anemone
Pictured in the latest installment of the AquaNerd Picture of the Week is a rose bubble tip anemone, but not just the regular old run of the mill RBTA. This anemone has bright red tentacles and a deep green color on its oral disc. This anemone isn’t a rare color morph by any means, but [...]
Picture of the Week, Marble Mouth Anglerfish
This week’s AquaNerd Picture of the Week is a reader submitted photo from our friend Louis-Pierre Rich. In the image, an elaborately camouflaged Marble Mouth Anglerfish (Lophiocharon lithinostomus), which faces the camera in case you can’t tell, is laying in wait for an unsuspecting prey fish to swim by so that it can be snatched [...]
Picture of the Week, Copperband Butterfly
Showing up in the latest AquaNerd POTW is a beautiful Copperband Butterflyfish (Chelmon rostratus) during feeding time at the Kemah Aquarium restaurant. This fish is a crowd favorite among aquarium keepers due to its coloration, but many will find it especially useful for its appetite for Aiptasia anemones. Despite their popularity, the Copperband can be [...]
