Reef Threads Plus #1


We are very pleased to present our first podcast in a new monthly series we’re calling Reef Threads Plus. In these podcasts we’ll choose a single topic and discuss it in depth with experts/knowledgeable people. For our first Plus podcast, Ben Johnson, Ret Talbot, and Jim Walters discuss what the hobby will be like if we reach a point at which we are no longer able to collect/import reef animals. As always, you can download the podcast here, or subscribe to our podcasts at iTunes. Also, follow us on Twitter @reefthreads. We hope you enjoy our new series, find it thought provoking, and will share it with others.—Gary and Christine

Sweet Coral Hind! A Colorful, Aquarium-Sized Grouper

Coral Hind or Miniatus grouper (Cephalopholis miniata)The name “grouper” conjures up images of underwater behemoths that no home aquarium can conceivably accommodate, such as the legendary goliath grouper (Epinephelus itajara). Fortunately, marine aquarium hobbyists who have a yen for these hefty predators can find several attractive, aquarium-sized species in the genus Cephalopholis, including the justifiably popular miniata grouper (C. miniata), aka the coral hind. Physical traitsC. miniata has a robust, bass-like body shape. It’s a mottled orange-red to scarlet in base color with myriad small, closely spaced, light-blue polka dots all over its body and fins.

Decisions, Decisions: New SAIA Tool Can Help Stock Your Nano Reef

Focusing on nano tanks, AquarioScenario is a new tool from the SAIA. Along the lines of their existing FishSelector, this interface offers the aquarium hobbyist guidance on selecting organisms for stocking a tank in an ethical and sustainable way, while avoiding impulse buying. AquarioScenario also incorporates the SAIAs ‘Lists of Unsuitable and UnsustainableSpecies’, and ensures the combinations of marine life suggested are suitable and compatible, considering not only size, but also behaviour and needs of the species. So, if you are feeling overwhelmed with the many decisions to make and options to choose from when planning your small reef, AquarioScenario can assist by suggesting possible combinations of marine life for each tank size range, while still ensuring an interesting display.

Life Discovered Under Antartica’s Ice

antarctica-fish-ross-ice_88132_990x742 Scientists have discovered an abundance of life living under Antarctica’s Ross Ice Shelf. It had been believed that nothing could survive under Antarctica until recently. With the ice sheet over 30 feet deep, and temperatures below freezing and no sunlight, it is shocking to find out there is flourishing life. The Ocean never stops amazing me.The discovery comes from the Whillans Ice Stream Subglacial Access Research Drilling Project (WISSARD). The project was the first to drill through the layers of ice to reveal the flourishing life underneath.… More:

What to Consider when Converting a Fish-only Tank to a Reef System

Evaluating your fish only aquarium and equipment is important before turning it into a reef“Caribbean Chris” and I are very frequently asked what it takes to convert a fish-only marine aquarium to a reef system containing corals and other sessile invertebrates. Can you just go ahead and add the invertebrates? Can you modify the existing system to suit the corals, or do you have to start the whole thing from scratch with a new tank and equipment? What has to change with respect to water conditions? Hopefully, the following points/suggestions will help address these and various other questions marine aquarium hobbyists often have when contemplating the transition from fish-only (or fish-only-with-live-rock) to reef:Pick a direction and do your homework Before making any new purchases or modifications to your existing aquarium, it’s important to pin down the type of reef system you want to keep. Are you primarily interested in soft corals?

CoralRX One Shots Are Back in Action After Re-release

After an apparent hiatus from the aquarium hobby (I say hiatus because of the “re-release” verbiage used in the promotional material), the One Shot single dose coral treatment from CoralRX is back and better than ever. These tiny little packets serve as a single dose coral dip that treats a wide variety of common issues (see the list below). And now they are in a much easier to use packet. Previously, the One Shots came in small glass vials, which weren’t always the easiest to open or the safest to handle

The Reef Table: Matt Wandell and the Hyperbaric Chamber of Secrets

 Happy Monday, Reefers! Here’s Episode 3 of ‘The Reef Table’ to help start off your week. This isn’t magic – just science!  I’m joined by Matt Wandell of the Steinhart Aquarium at the California Academy of Sciences and Lemon Tea Yi Kai of Reefbuilders to dive a little deeper into the topic of deep water fishes. We’ll go over the various methods of collection, the challenges associated with said methods, and what really cool fish come from the ‘Twilight Zone’. I hope you’re ready to get geeky. You guys on the Northeast coast? We have a nasty blizzard honing in so you have no excuse not to sit back and watch – stay warm and enjoy! Have any questions or topics you’d like to see discussed?
