The answer to the struggle of what to feed marine predators that require live foods is right under our noses. Fish might be friends, but in the real world the may also be food.

Back in March, I wrote about Chad Vossen feeding a platinum clownfish that was to be culled to juvenile Dwarf Cuttlefish, Sepia bandnesis, and talked about how clownfish destined to be culled might be a great source of marine feeders for predatory marine animals. As a follow up I present to you the below video: Dr. Seuss eats Nemo. In the video I feed my pair of Dr. Seuss Fish, Belonoperca pylei, some captive bred designer clownfish that were raised in quarantine conditions, and were destined for the culling block. These clownfish were provided to me by Bay Area Reefers President, Steinhart Aquarium Volunteer (Thanks David!) and clownfish breeder extraordinaire, David Sheh.

Feeding marine predatory animals can be difficult because finding appropriate live foods can come with all kinds of problems. Availability can be challenging, as finding the right size prey items, in the quantity you need them, when you need them can be problematic. Disease and parasites from wild caught prey items can infect your predatory fish, and quarantine of such animals is and added expense, as well as taking up time and resources.  Worse, the ethical issues surrounding wild caught feeder animals are significant; using animals flown halfway around the world as feeders seems exceedingly wasteful.  Furthermore, with some aquarium fish potentially to be listed as threatened or endangered in the endangered species act, the practice of feeding out wild caught animals can become even more inflammatory. Cultured freshwater prey items don’t offer a great alternative as they can have a different nutritional profile from saltwater prey items, and can present sub optimal results – for example, in my experience Dwarf Cuttles fed solely freshwater ghost shrimp tend to lay much fewer eggs, and fewer viable eggs than cuttles fed saltwater shrimp.

If only there were a whole bunch of captive bred, saltwater animals that nobody wanted, weren’t sellable, and were often culled as a matter of course. Oh wait. There are.

Most marine aquarium hobbyists purchase animals for their tanks without much thought to those animals’ origins. This is understandable since most local fish stores and online retailers don’t make that kind of information easily available to customers. Point-of-origin does matter, however, because not all animals are collected sustainably and not all fishers are treated equitably.

The marine aquarium hobby and its practices are increasingly scrutinized by anti-aquarium trade activists and environmental advocacy groups, wildlife managers concerned about invasive species introductions and legislators interested in pleasing constituents. A sustainable and equitable trade is a defensible trade; the status quo is not. More important than defense, however, we argue that purchasers of wild animals have a responsibility to know where their animals originate, how they are collected and handled, and what the trade’s effects are on reefs and reef-side communities. It seems that aquarists have a responsibility to treat the animals collected from the wild as the precious commodities they are instead of curios traded for pennies on the dollar.

If you know where your animals originate, you often have a better idea of howthey were collected and treated through the chain of custody. This should be important to every aquarist because a poorly treated animal is less likely to live or thrive.  More »

ulufeke 300x225 The Top Five Speakers I Cant Wait to See!: Grand FinaleHere we go, guys, the final round of my Top Five! This particular speaker sparked my interest not too long ago, based not only on the strides he’s made in the aquarium industry and his fascination with my absolute favorite thing ever- Cephalopods, but for how he came to be the Octo-Guru he is today. Richard Ross, Senior Biologist at the Steinhart Aquarium in the California Academy of Sciences, actually kicked off his career in a comedic fashion in the form of juggling and improv while pursuing a degree in Philosphy instead of the expected field of Biology. Eventually establishing himself as a full -time entertainer, he also began exploring the arts of glass blowing, founding his own glass blowing studio in Alameda, CA. After the birth of his daughter, Ross left his career as an entertainer and fulfilled the duties of a stay-at-home dad, where he was able to completely engulf himself in the beauty of the reef keeping hobby. He eventually made incredible breakthroughs in keeping Sepia bandensis, the Dwarf Cuttlefish, documenting the entire process. Rich began volunteering at the Steinhart Aquarium in 2003 after a divesting earthquake forced the animals to be moved to a holding facility. After years of volunteering and part-time employment, in 2008 he was offered an opportunity he could never turn down – the full-time position of managing their 212,000 gallon Philippine Coral Reef and associated exhibits. I haven’t had the pleasure of viewing this phenomenal system in person, but it’s on my list for this upcoming year. The reason this all fascinates me so much is I myself started of on a vastly different career path before I found myself here, writing this. While I’ve always had a passion for the ocean and it’s occupants, and my first job was scrubbing algae and doing water changes at the local fish store, I ended up following the culinary road, with a degree in Professional Cooking. Unhappy with the field I found myself itching to get back into Reefs, discovered my love for the Octopus, and quickly started following Ross’ career. Needless to say, I consider him a huge influence in my endeavors. This year, he’ll be speaking about Phosphate, what it means, and how it effects your reef systems and how it influences a thriving tank. It’s going to be riveting, I seriously am jumping up and down with glee for this one. For more about Rich and his career path, check his website here.

From Ret Talbots blog – 
My latest article, co-authored with friend and colleague biologist Richard Ross of the Steinhart Aquarium, published yesterday in Reef Hobbyist Magazine. In some ways, it represents a departure from my regular beat, and I thank editor Jim Adelberg for the concept and invitation to write the piece.

The Editors Note: In Skeptical Reefkeeping IX, Rich Ross is joined by our old friend Chris Jury as they try to come to terms with the “impossible” yet confirmed PO4 readings in Rich’s gorgeous reef. The analysis is thorough, thought- provoking, grounded in science and suggestive of a far more complex picture regarding PO4 and its role in our aquariums.

There are many standard parameters in the reefkeeping world that aquarists strive to match in their home reefs – water quality, light spectrum and intensity, and water flow, just to name a few. Rarely do we stop to think where these standard parameters come from, and even more rarely do we consider calling into question the utility of these parameters. This can lead to aquarists ‘chasing numbers’; tweaking water parameters to hit a standard goal. Often times, people think that hitting a magic number will inherently result in a better, healthier tank. In the past few years, dealing with phosphate in saltwater aquariums has become one of the most talked about ‘must control at all costs’ parameter, and in this installment of Skeptical Reefkeeping, we will look at some evidence which calls into question the reliability of testing, the generally accepted target phosphate concentration, and general control of phosphate in reef aquariums.


Rich’s 150 gallon display, on a 300 gallon system, is running a phosphate level of 1.24 ppm, a level at 24.8 times higher than the often recommended .05 ppm. Photo by Richard Ross.
