Orchid Dottyback: Hardy, Peaceful, and Just Right for Reef Tanks

Orchid Dottyback (Pseudochromis fridmani)Captive breeding of marine fishes has been a boon to our hobby in any number of ways, one of which is democratizing access to formerly really pricy species such as the orchid dottyback (Pseudochromis fridmani). While I wouldn’t characterize the current market price of this Red Sea species as “cheap,” it’s definitely in the realm of affordable for most hobbyists—and it’s hardiness, ease of feeding, manageable adult size, reef-friendliness, and relatively peaceful disposition (as dottybacks go, that is) more than justify the modest outlay of cash for a specimen. Physical traits P. fridmani is a small (reaching only around 2½ inches), streamlined fish with reddish-purple overall coloration and blue scale margins. A dark stripe extends diagonally from the snout upward through the eye. This species’ appearance in aquariums can vary markedly depending on the lighting scheme. Feeding You’ll find this P

Good at Gardening? Try Reefkeeping!

If you’re a gardener with a green thumb, making the leap to reefkeeping isn’t as far as you might think!Having once worked in the nursery and landscaping business, it often occurs to me that there are a surprising number of similarities between terrestrial gardening/landscaping and reefkeeping. I would even suggest that, in some ways, reefkeeping has more in common with gardening than with maintaining a freshwater or marine fish-only aquarium. Many of the elements terrestrial “green thumbs” must deal with in order to succeed with gardening have analogs in the reefkeeping hobby, and I’m convinced that if gardeners could be persuaded to give reefkeeping a try, they might just discover they have a certain knack for nurturing coral “gardens” as well. Now, I fully understand that corals aren’t plants and that this analogy only goes so far. Nonetheless, the following factors that are important in both gardening and reefkeeping might just strike a chord with some of you horticulture aficionados out there: Proper spacing Knowing the height, spread, and particular growth habit of a plant is critical in determining where in the landscape it should go and how far to space it from other plants. Similarly, reefkeepers need to know the potential size, growth habits, and defensive capabilities of corals and other sessile invertebrates (e.g., plating, encrusting, sweeper-tentacle-producing, etc.) so they can space them out properly in order to prevent them from stinging, shading out, physically growing onto, or otherwise harming/impeding one another. Proper sun exposure Sure, gardeners don’t have to pay the long dollar to replicate natural sunlight the way most reefkeepers do, but like reefkeepers, they do need to research and adhere to the lighting requirements of the specimens they choose. Just as gardeners soon discover that plant species vary considerably in their lighting needs (ranging from shade-loving hostas to sun-hungry spireas), reefers quickly learn that some sessile invertebrates, such as Acropora, prefer relatively intense lighting; others, such as mushroom polyps, favor more subdued lighting schemes; and still others fall somewhere in between these two extremes. Proper wind exposure Okay, I’ll admit there’s no wind underwater, but there is most assuredly an analogous element: current. It’s a very small leap from planting terrestrial plants where they’ll receive an appropriate level of wind exposure (for example, placing azaleas and other broadleaf evergreens where they’ll have some protection from drying winds) to positioning different sessile invertebrates where they’ll get a species-appropriate amount of current

Leptoseris: A Stunning Newcomer to the Reefkeeping Scene

Jack-o-Lantern color morph of LeptoserisWhen you have been in the hobby a long time, you tend to see a lot of the same things over and over again. I often become desensitized to some of the most beautiful fish in the world because I’ve seen them so many times over the course of 30 years (mandarin dragonets, for example). When something new comes along, it almost is immediately eye-catching. After all, it’s not that common to have a completely novel fish or coral emerge in the trade. We are fortunate now to have a relative newcomer to the hobby available—the coral Leptoseris. The common name for Leptoseris is “wrinkle coral”; however, I have never heard anyone refer to it as such.

Eshopps Adding Some Style to Refugium Lighting

Many marine aquarists illuminate their refugia with the most basic of lighting systems. These usually consist of an aluminum shop light and a compact fluorescent bulb, which isn’t exactly the most visually appealing arrangement. Eshopps is looking to change all that, however, with the upcoming release of their yet to be named LED refugium light. This sleek little fixture sports a razor thin design that sports the signature blue coloration that permeates thought the entire Eshopps lineup. It has a footprint of 5″ x 4″, with a thickness of just 5/16th of an inch. Helping the light to jut out over the water is a mounting bracket that blends right into the fixture and can affix to acrylic or glass of varying thickness thanks to nylon thumbscrews. Getting back to the fact that the refugium light is without a name, Eshopps is looking for a little help in the creativity department.

Refugium Lighting

Refugium Lighting Refugiums are a great way to grow Algae for filtration, food, and provide excellent breeding grounds for pods, shrimp, and anything else that would otherwise be destroyed in your Display tank. Refugiums are not always designed for filtration. Some are designed purely for visual enjoyment and others are home to coral frags as they grow larger. They also make great Time Out spots for bad fish and are good places for injured fish to heal, but remember these are connected to your Display tank so They will not count as quarantine or hospital tanks. There are 2 main types of Refugium Lighting Plant Based- These refugiums are generally places for Macro algae like Chaetomorpha or Caulerpa. Mangroves are also grown in refugiums.

Discosoma Mushrooms: Beautiful, Adaptable, Beginner-Friendly Corals

Discosoma mushrooms look great and are tolerant of varied aquarium parametersSome of the most beautiful creatures in this hobby are neither rare nor difficult to keep but get glossed over by experienced reef aquarists because they are not the “latest and greatest” coral specimens that landed on our shores. So today, I want to talk about Discosoma mushroom corallimorphs because they are both excellent for beginners and stunning to the eye. Excellent beginner coral First off, Discosoma are corallimorphs, not true corals. They share traits in common with both corals and anemones yet are distinct enough to warrant their own classification. What does this mean in terms of care? Nothing really. Discosoma are some of the easiest additions to our reef tanks.
