You Asked Us…So We’ve Answered!

An interior spread of The Salt Smart Guide to Preventing, Diagnosing, and Treating Diseases of Marine FishesSince we released The Salt Smart Guide to Preventing, Diagnosing, and Treating Diseases of Marine Fishes eBook earlier this year, the support from readers has been unequivocally positive. But, what’s the one thing that’s been requested many times since then? A print version – so folks could add it into their aquarium library! It’s totally understandable, Jeff and I had both toyed with the idea of adding a tangible version onto our respective aquarium collection shelves, too. In this extremely digital age, there’s still something very fulfilling about flipping open a great aquarium book while doing research or passing the time on a rainy afternoon.Today we’re happy to announce the print version of The Salt Smart Guide to Preventing, Diagnosing, Treating Diseases of Marine Fishes is now available! The beautifully printed, full color, 194 page book is jam-packed with the same great content as the eBook and is delivered right to your door from our printer. You can learn more about the book and purchase it here: As a thank you to our readers who are among the first to purchase the print version, use discount code U6GNSK2K to save $5 at checkout

The Evolution and Biogeography of Stonogobiops – part 1

 The shrimpgobies of the genus Stonogobiops are a common sight in any aquarium store, with species oftentimes selling for not much more than the cost of a cheap damselfish. Because of this, it might come as a surprise to learn that the half-dozen species that comprise the genus were completely unknown to science as recently as the late 1970’s! The Filamented Shrimpgoby (S. nematodes), a particularly ubiquitous and affordable species in our hobby, was originally known from just a single specimen. So how do we explain this apparent contradiction between the rarity and monetary value of these fish? Clearly, our knowledge of how to locate these fishes in the wild has improved drastically. Unlike some of their close relatives, Stonogobiops is primarily found at… More:

New Era Aquaculture reborn as World Feeds

Yorkshire-based fish foods company New Era Aquaculture Ltd has been sold out of administration and a new company, World Feeds Ltd has been set up backed by sizeable financial investment which will facilitate a major expansion plan for the re-born operation. All existing staff have been retained by World Feeds and the products have been re-branded as Vitalis Aquatic Nutrition in the UK and in the rest of the world, and will be known as Balance Aquatic Nutrition in the USA. New Era had been burdened with the cost of trademark litigation in the US, which led to the appointment of administrators.  It was sold to World Feeds, the new company supported by investment from Finance Yorkshire.

Pocillopora Corals: Hardy, Adaptable Reef Architects

Pocillopora corals are productive reef builders in the wildYou may not be aware, but Pocillopora, despite being among the less popular stony corals in the reef aquarium hobby, are second only to Acropora in reef-building productivity in the wild. Their skeletons make up a huge portion of the reef’s structure in the ocean. Pocillopora are also among the most adaptable SPS corals in that they tolerate a wide range of both light and flow. At Tidal Gardens, we grow them under medium light and medium flow, but they do develop better coloration under stronger light. If you want to experiment with stronger light, be sure to acclimate the coral slowly to the light because it is possible to burn them if done too hastily.The other aspect that makes Pocillopora highly effective reef-building corals is their growth rate. They are among the fastest-growing stony corals and have a trick up their sleeve if things go downhill—they can reproduce asexually by means of “polyp bailout,” where each polyp can detach from its skeleton and drift to a new location to colonize. While this technique is not unique to Pocillopora, these corals do it far more effectively than others.

Stranded Killer Whale Saved By Onlookers

Let’s admit it, we all love Orcas aka Killer Whales.  Well then we should commend a group of brave volunteers who did an amazing job working to save a stranded Orca on July 22nd on the rocks near Hartley Bay, BC Canada.  The whale-loving citizens spent over 6 hours working to keep the killer whale cool and wet with the hopes of saving it from an uncertain fate. orcaMore:

Juvenile Trumpetfish

Good morning friends, many have written and asked what kind of fish is always floating in front of our LIVE underwater online video camera that we have at 50 feet out in front of our Substation lagoon. Well as you can see from the photo I took on friday it’s a little reddish/brown trumpetfish which has decided this camera is perfect for his new home. When I went out to take the photo he was right in front of the camera lens as you see here with his head down and tail straight up to the sky but as I got closer he drifted behind the camera and stayed there until I was gone. From a distance I watched as he then came back to the exact location and continued to hang there upside down, what a cool little fish. Pretty amazing that this fish can get up to three foot long! For your chance of spotting him just go to…… Waking up tired today from a long 40 mile mountain bike ride yesterday that I did with three other friends and countless other activities during the day…

Dr. Seuss is back!

dr seussThe first new book in 25 years by Dr. Seuss, aka Theodor Geisel, will debut July 28. “What Pet Should I Get?” features the spirited siblings from the beloved classic “One Fish Two Fish Red Fish Blue Fish” and is believed to have been written between 1958 and 1962. 

“Ted loved and had pets himself, as a young boy on up through adulthood, and that makes the wonderful excitement and buzz for this new book all the more special,” said Susan Brandt, president, licensing and marketing of Dr. Seuss Enterprises.

Geisel’s widow, Audrey Geisel, found the manuscript and illustrations in their California home soon after her husband died in 1991. The materials were set aside and then rediscovered in 2013. Random House Children’s Books said in February that it expects to release additional books from the found materials.

It only seems to prove the siblings’ lesson from “One Fish Two Fish Red Fish Blue Fish.”

from here to there,

funny things

are everywhere.”… More:

Is It Okay to Quarantine Multiple Marine Fish at Once?

Sometimes QTing multiple saltwater fish in the same tank makes sense, other times it doesn’tAs regular Saltwater Smarts visitors are well aware, “Caribbean Chris” and I are strong proponents of quarantining all newly acquired fish for at least four weeks before introducing them to a display tank. But what about keeping two or more fish in the same quarantine tank (QT) simultaneously? Is that an acceptable practice? The answer to this question, as with so many aspects of marine aquarium keeping, depends on a variety of factors. Before proceeding with multiple-specimen quarantine, ask yourself these questions:Am I doing this just to save time in stocking a new tank? When contemplating the necessarily drawn-out process of quarantining all the livestock for a new display system, it might be tempting to think, “Hmm, if I just put all the specimens into quarantine at once, I can have a lively show tank in no time!” But this ignores the fact that whether you put all the specimens into the QT or display tank simultaneously, one sick fish among them will still infect the rest. is the world's leading destination for sustainable coral reef farming and the aquarium hobby.
