The Use of Negative Space in the Reef Aquarium Aquascape

Marine aquarium aquascapes are evolving to favor more open, irregular aestheticsOne of the more interesting developments in the reefkeeping hobby, in my opinion, has nothing to do with the latest, greatest gadget or advance in water-quality-management methodology. Rather, it’s an evolving aesthetic in aquascaping. Bored with the traditional monolithic stack of rocks propped up against the back pane and consuming much of the tank’s volume, modern reef hobbyists are starting to appreciate and experiment with the use of negative space—the open areas around the rockwork—when planning their aquascapes.The towering, uniform “wall of rock” has given way to lower-profile aquascaping with irregular, broken topography, allowing open channels and swim-throughs, caves and overhangs, islands, etc. And this trend makes perfect sense. Artists have long known the value of striking the right balance between positive and negative space in their compositions. With our reef systems essentially being living works of art, it stands to reason that the aesthetic principles guiding the works of painters and sculptors can only make our aquascapes all the more visually appealing. This aquascape features a broken topography and plenty of open sand What’s different about exploiting negative space in reefkeeping versus artwork is that it has both practical and aesthetic value

Reef Threads Podcast #250


Should we take marine animals from the reefs for our viewing pleasure?

In our 250th podcast, a discussion about marine-fish captive breeding and Orca breeding leads to an exchange about keeping wild animals captive, the current state of our hobby, and how collecting and keeping marine animals fits in the larger animal-treatment arena. Basically, we address some difficult questions. After you’ve listened, share your thoughts here or on the Reef Threads Facebook page.

Is the Internet a Viable Resource for Marine Aquarium Research?

Virtually since the advent of the internet, there’s been a tendency in our hobby to rate the reliability and trustworthiness of online content beneath that of print-format materials—books, magazines, and so forth. But is this assessment really fair?The general premises behind this viewpoint are: Anyone with a computer and internet connection can post anything they want online, whether or not he or she has the requisite expertise to expound on the subject. Online articles and posts are seldom given professional editorial treatment and/or subjected to peer review, so you can’t trust that they’ve been vetted properly for accuracy. There tends to be an “echo-chamber effect” online, so inaccurate or outright fallacious information appearing on one site can be picked up immediately by others and repeated ad nauseam, creating the false impression of consensus on the information/viewpoint. Now, there’s truth to each of these arguments, but as someone who’s made his living as a writer/editor for nearly 20 years (primarily in print format) and once served on an editorial committee that reviewed book submissions for a major retail pet chain, I can say with some confidence that print materials have their limitations as reference sources, too. Among them: Just as with online materials, print books and magazines are no more reliable or accurate than the writers and editors who produce them. You can’t assume that just because someone went to the effort to produce something in hardcopy, the information it contains was properly vetted.
