Different Macroalgae for Different Situations
A refugium with macroalgae is almost a must in our controlled and complex marine biological systems. Along with skimmers and various types of media reactors, refugiums help pull unused nutrients out of the water column as the desirable algae grows. These nutrients are known to break down into ammonia, nitrite, nitrate and phosphate, which can [...]
Back and Forth Banter on Hawaiian Aquarium Ban in Video
We recently discovered a little video dialogue from C Harding Productions showing both supporters and opponents of aquarium collection in Hawaii. The arguments are fairly well represented from both sides, as experts from different viewpoints chime in as to why each issue is important. We get to hear the typical points, but one individual struck [...]
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 [...]
Stunning Royal Gramma Dejongi Hybrid Seen on Video
We first spied the stunning Cuban Gramma dejongi basslet almost two full years ago. And even though we’ve seen plenty of images and videos of these amazing and virtually unattainable fish since then, we still can’t seem to get enough. Unfortunately for our addiction, the story doesn’t stop with just this species, as it gets [...]
Tip of the Day – 1/29/2012
Want a quick and easy way to maintain calcium levels in your aquarium? Try adding a canister filled with aragonite-based media to your RO/DI filter.

The particular individual that caught our eye this time around is an orange colored lemonpeel angelfish (Centropyge flavissima var.) taken from somewhere in the [...]
Xanthic Scopas Tang Shows Up at RVS Fish World
Scopas tangs (Zebrasoma scopas) seem to come in an unending variety of colors and patterns. Whether they be hybrids between two similar species, multicolor mutatants, or just different enough to catch our eye, the fish continue to be walk that thin line between what is considered uniquely beautiful and grotesquely bizarre. The latest Scopas weirdos, which come [...]
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 [...]

Europe is about to get a fresh dose of cherries with the help of US-based dealer of top shelf corals, Cherry Corals. The purveyor of amazing coral frags is expanding its operations overseas with the help of an unspecified business partner. And by working directly with their collectors in areas like Australia and other parts [...]
Excess Carbon Dioxide Causes Clownfish to Act Drunk
You know that lightheaded feeling you get when you hold your breath for too long or hyperventilate? Well, those dizzying feelings are a side effect of excess carbon dioxide building up in the blood, and it apparently causes fish to get funny feelings as well. According to a recent story on NewScientist, scientists at James [...]
