This is a video of a big aquarium – doesn’t a little information about how its run and how the animals are cared for make it more exciting?

Like many of us, I have been thinking about the new television show TANKED. The great discussion so far about the show has been really illuminating and taken the reefkeeping community beyond issues like ‘This coral is cool’ or ‘what’s the newest product’ or ‘where do I get the cheapest…’. I think this kind of big picture discussion has been relegated to dusty, quasi philosophical forums with low readership and I think getting some of this discussion out in the open can do nothing but  befefit the hobby in the long run by forcing more of us to think about issues on the broader stage. The critical thinker in me (ah the Philosophy degree is worth something – see mom and dad!) is also thrilled that hardly any of the discussion I have seen has not degenerated into ad hominem attacks, and that people have been genuinely  playing with the ideas rather than trying to score points. In these respects, I think TANKED has been great for the hobby.

In other respects, I am on the fence about the show. More »

Now, that’s reefkeeping education!

Some reefkeepers feel the need to justify their aquariums, they seem to feel the need to make their home tank more than a hobby. I can understand that feeling, especially in the face of those who characterize the way we get the animals for our boxes of coral as ‘raping the reef’ and the massive amount of resources that often go into keeping a home tank. However, if that justification is really empty, if it isn’t a real justification, it can serve to make the justifier and the hobby in general look worse.

The most popular justification that people seem to use when trying to justify keeping exotic fish and coral in their living rooms is that their home reef tank  somehow serves the wider community because it is educational. ‘All of the people who come through my home ask questions about the reef’ they say, but does that really count as education? I don’t think it does, in the same way that showing visitors to my home photographs of my trip to Komodo doesn’t count as education about that area of the world. Its nice, they may glean something form the interaction, but is it really educational in the same way Public Aquariums, workshops, conferences, reef club meetings or science classes count as education?

In the previous installments we talked about skeptical methodology and how it can be used to sort through the overwhelming amount of reefkeeping information that is now at the virtual fingertips of reef hobbyists. We also discussed how skeptical thinking has impacted the idea of sustainable reefkeeping, scientific terminology, magic products and more. In this installment we’ll take a look how to decide which expert to listen to and the most important tool in the skeptical reefkeepers toolbox.

A brief reminder to set the scene

Skepticism is a method, not a position. Officially, it’s defined as a method of intellectual caution and suspended judgment. A skeptic is not closed minded to new ideas, but is cautious of ideas that are presented without much, or any, supporting evidence. In our hobby there are tons of ideas presented without much, or any, supporting evidence. Being a skeptical reefer essentially boils down to taking advice/products/new ideas with a bucket of salt. Being a skeptical reefkeeper requires that you investigate why, how and if the suggested ideas actually work. As a skeptical reefkeeper, you decide what is best for you, your animals, and your wallet based upon critical thinking: not just because you heard someone else say it. The goal of this series of articles is not to provide you with reef recipes or to tell you which ideas are flat out wrong or which products really do what they say they do or which claims or which expert to believe – the goal is to help you make those kinds of determinations for yourself while developing your saltwater thumb in the face of sometimes overwhelming conflicting advice.

Experts

In any endeavor, it is always great to be able to consult with someone who has more experience than you do. There is no need to reinvent the wheel, and avoiding avoidable mistakes can save you time and money, as well as lives of animals. However, there are ‘experts’ everywhere you turn, and it can be difficult to know who’s expert advice is worth listening to and who is just spouting opinion or perpetuating something they heard somewhere under the guise of being an expert.

In this installment we’ll take a look at some of the terminology that is used in reefkeeping and see if the terms make sense or are misleading (potentially, accidentally, or purposefully).

Words words words

This is a photo of and elephant seal and has nothing to do with this article.

Our hobby is constantly evolving, and the terms we use to communicate ideas to one another change and morph over time and these changes can lead to confusion. For instance, the term refugium initially referred to an area of a system that small animals could use as a refuge from predation, but now refugium also refers to an area of the system used to grow algae for nutrient export or simply a small tank plumbed into a larger system. The ideas can overlap, but they don’t necessarily, so when someone asks for information on setting up a ‘fuge, it becomes important to know what the term means to them in order to help them with information relevant to their needs.

In the previous two installments of Skeptical Reefkeeping, we talked about how applying skeptical thinking to reefkeeping can help you make decisions about what methodology to follow or which products to use. In this installment, we’ll spend less time exploring the skeptical method, and instead examine how skeptical reefkeeping has impacted, and continues to impact one particular aspect of our hobby: making our hobby more environmentally sustainable.

That sounds like work! Just tell me what to do!

Sorry, I can’t just tell you what to do. I wish I could, but there is that whole Biblical quote “Tell someone what to do and their fish and corals die, get them to understand the bigger complex picture and their fish and corals live”. This hobby is not simple and there are as many opinions about how to keep our glass boxes thriving as there are people with glass boxes. The goal of this series of articles is not to necessarily provide you with reef recipes or to tell you which ideas are flat out wrong or which products really do what they say they do or which claims or which expert to believe – the goal is to help you make those kinds of determinations for yourself in the face of conflicting advice.

The drama of ‘juicing’ fish

The early 80’s was a time of glam rock, hardy elegance corals, and DIY sumps filled with hair curlers for bio media. Back then, rocks covered with hair algae were lovely, panther groupers were the hot fish, and aiptasia were considered fabu. Hardly anyone stopped to think about where animals for our reef tanks were coming from…we were all too busy just trying to keep them alive for more than a month. Fish would come into the LFS; some would make it, and some would slowly waste away despite eating well. Most of us figured we were making some husbandry mistake that resulted in the death of the fish. However, some began to apply skeptical methodology to the problem and hypothesized that the issue might have something to do with the way the fish were being handled somewhere along the way to the LFS.

Cyanide fishing kills fish and corals – which hardly seems to justify the lower prices the practice can create.

It turned out that they were right. Investigation revealed that cyanide, often called ‘juice’ was used to ‘knock out’ fish to make them easier to collect. Sounds good right? Easier to collect means cheaper, cooler animals, and everyone wants cheaper animals. However, the monkey wrench here is that cyanide is a poison that doesn’t necessarily kill the fish outright. Often, the fish seems to recover from the initial shock. It can make it all the way through the chain of custody from the collector to the exporter to the importer to the LFS to the hobbyist tank before it begins to go down hill. We now know that the cyanide can damage the fish’s ability to adsorb food; it can eat like a pig, but get little of the nutrition it needs to live. Eventually, the animal can starve to death. More »
