The pair of yellow wrasses attempting to spawn after the lighting change in my aquariumThe other night, as I was watching the debate on TV, I noticed that my reef tank got darker. Just a little, but it was darker and yellower. I opened the front (it is in a wall) and noticed that half the LEDs were out. “Okay, no problem,” I thought. “I’ll fix it in the morning.” The lights were about to go out anyway. As I watched, I noticed that my pair of fire clowns, which have a love-hate relationship, looked like they wanted to spawn. The larger one was trying to entice the smaller one into a bottle “cave.” The smaller one eventually followed, and the pair spent “time in the bottle” (reminds me of a song), swimming very close to each other, although I couldn’t hear what they were saying.As I was watching the clowns, I couldn’t help noticing that my pair of bright yellow wrasses was also attempting to spawn. by Saltwater Smarts | Oct 30, 2015 | Equipment, Reef, Science, Tanks
Aquascaping with dry rock has a number of advantages and disadvantagesWhen aquascaping their tanks, marine aquarium hobbyists have the option of using live rock or dry rock (or some combination thereof) to create the foundational reef structure. Each of these options is completely workable but, as with every aspect of this hobby, has its own set of advantages and disadvantages. So how to choose which approach might work best for you given your unique circumstances, budget, etc.? To aid in your decision making, let’s explore the pros and cons of each approach, beginning today with the use of dry rock. I’ll tackle the plusses and minuses of live rock aquascaping in a future post.Pros of dry rock aquascaping Dry rocks tend to be easier on the pocketbook. One reason is that they ship dry so you’re paying only for the weight of the rocks, not the added weight of water as with live rock, and there’s no need to shell out for expedited shipping. Also, the better-quality dry rocks on the market tend to be less dense than live rock, so you get a greater volume of rock for your aquascaping dollar. by Saltwater Smarts | Oct 26, 2015 | Corals, Equipment, Fish, Opinion, Reef, Science
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 by Saltwater Smarts | Oct 17, 2015 | Equipment, Fish, Science, Tanks
The Avant-Garde Marine Aquarist – now available in print and eBook formatsThink you’ve got equipment woes? Imagine what it would have been like trying to equip a marine system back at the dawn of marine fishkeeping! Well, hobby pioneer Paul “Paul B” Baldassano doesn’t have to imagine that because he was there to witness it. (Actually, he may have been there when our first human ancestor slithered out of the primordial ooze—we’re looking into it.) To get a sense of the equipment challenges early hobbyists faced, check out this excerpt from the first chapter of Paul’s new book, The Avant-Garde Marine Aquarist: A 60-Year History of Fishkeeping, now available in both electronic and print formats:Equipment limitations Early tanks had other concerns besides parasites, and the majority of those concerns were due to the aquarium hardware at the time. As I said, tanks had metal corners up until the early 60s, which was when all-glass tanks were sold. That led the way for larger tanks to be manufactured. My first all-glass tank was a 40-gallon, which was considered large then by Saltwater Smarts | Sep 24, 2015 | Corals, Equipment, Fish, Invertebrates, Opinion, Science, Technology
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.
