Honeycomb Cowfish, Acanthostracion polygonia

Good morning friends, I have a pair of Honeycomb Cowfish, Acanthostracion polygonia for you all today that I photographed just moments before sunset. Every day here on the Caribbean reef around dusk many species of fish set out to find a mate and spawn before sunset, it’s by far the best time to be out with a camera. These unique looking box shaped Cowfish usually spend the day by them selves but around dusk will set out to find a mate. Once found the Male (in front) usually starts the courtship ritual by bumping into the female, swimming fast circles around her and showing off his beautiful electric colors which they can change in the blink of an eye! These fish are fairly uncommon to see and I have never found a baby one, it’s on our top 10 hardest fish to find list MORE

 A scientific course for all levels of divers, what a good idea!  Rendezvous Dive Adventures staff and staff from The Seattle Aquarium have teamed up to offer this training.   Shawn Larson (Curator of Research) and Jeff Christiansen (Dive Safety Officer) will be on site to teach you the survey and diving techniques. The main focus is rock fish surveys, but the principles and methods can be used for many other survey subjects. MORE

Study Examines Influence of Aquarium Fish Collector Preferences on Catch

 Generations ago, aquarium fish keepers may have seen themselves as sharing little more than a “pastime”. But, with the rapid growth of marine aquarium keeping that began in the late 1980’s, we came to see ourselves as participating in an industry as well as a hobby. Today, we hobbyists are growing increasingly aware not only of our stake in the aquarium industry but in global marine fisheries. This, of course, has all come in the wake of sometimes heated public debate concerning the impact of ornamental fish harvests on coral reef habitat. As we–consumers of marine ornamental fishes–continue to examine how our habits mold this industry, we should probably remain especially cognizant of current fish collection practices. Some speculate that in the case of fisheries management, it may be more important to understand MORE

What Gives When Herbivores Won’t Graze Nuisance Algae?

Some yellow tang (Zebrasoma flavescens) specimens devour nuisance algae, while others do not.The practice of adding herbivorous fish and/or invertebrate species to marine aquariums for the purpose of nuisance algae control is quite commonplace. Hence the popularity of those herbivore packages known in hobby parlance as “cleanup crews,” or CUCs. But almost as common is the experience of adding a herbivorous species or CUC to eradicate algae only to discover that it doesn’t quite live up to expectation. Why does this sometimes happen? Here are a few possibilities: The alga isn’t on the menuWe like to think that herbivores will feast on any and all algae put in front of them, but most are more discerning than that. For example, many herbivorous fish and inverts may do a great job of grazing diatoms and algal films but then completely ignore the forms of most concern to hobbyists, such as those tough, unsightly strands or clumps of hair-type algae. In fact, my experience with marine herbivores in general is that few will actually outright consume growths of hair algae MORE

Thomas Brown Joins Salty Supply

We’d like to pass along congratulations to our friend Thomas Brown for his recent appointment to Lead Video Content Director at online aquarium retailer, Salty Supply. Thomas has produced a wide variety of video content ranging from numerous web series (The Aquarium Report, The Ultimate Tank Build, etc.) and LFS/manufacturer spotlights to product reviews and event coverage. He has also worked with a variety of brands, such as LRS Foods, Aqua Medic, Orphek, AlgaGen, and Polyp Lab. Over the last few years, Thomas’ progress and creativity caught the eye of Salty Supply CEO, Richard Gilliland, who reached out to Thomas with an interest in making him part of their team.I am so excited to start this new venture with Salty Supply. Over the past two years I’ve worked really hard to bring value to the ThomasVisionReef subscribers. I am truly honored that Richard and the rest of the Salty Supply team have taken such an interest in my work not only as a YouTube Content Creator but as a brand builder.

Be a good aquarist.

Tartaruga-marina1In many ways the future of the marine aquarium hobby lies within every hobbyist. Whenever an environmental challenge is faced, often artists and musicians pose the question, “What will we tell our children.” Where I live in Maryland, natural gas collection via a method called hydraulic fracturing is up for debate, as our mountain region lies over rich gas shale. As it appears that fracturing is more imminent by the day, Facebook is littered with posts asking what our children will say, if their mountaintop home is destroyed by greedy gas companies. It’s a logical question, and as I watch my nearly three year old daughter stare into my aquariums, fascinated by the diversity of life, I wonder what I will tell her if by the time she’s my age, coral reefs and oceanic ecosystems are in total collapse. While coral reef aquarists aren’t the primary force driving oceanic decline, we are intricately connected to it, whether we opt to face that reality or not. While reef aquarists may not be able to reverse trends of oceanic destruction, we can change our hobby for the better. Without individual hobbyists and consumers, the reef aquarium industry is doomed to fail. Without a demand for live fish and corals, there would be no need for collection. So what can we do, what sea change of thought is necessary to elicit change from our industry and across the wide ravine of marine aquarists?  MORE is the world's leading destination for sustainable coral reef farming and the aquarium hobby.
