Commercially Available Porkfish

Figure 1. Captive bred Porkfish juvenile available fromFishEye Aquaculture. Three years ago we posted a blog stating the commercial production potential of Porkfish, Anisotremis virginicus (Porkfish Protocol – Rising Tide’s First Commercial Species). As you’ll recall, researchers at the Tropical Aquaculture Laboratory collected eggs spawned at SeaWorld Orlando and grew them to the juvenile phase and beyond. This was not the first time that Porkfish had been grown in captivity (again credit goes to Martin Moe and company). It was, however, the first time that Porkfish had been grown from eggs spawned in captivity using standard commercial production protocols; including the use of hatchery grown live feeds (rotifers and Artemia). This proved inspiring to one of Rising Tide’s industry partners who decided to add this fish to their list of available species. Figure 2.

Top 10 Zoanthids and Palythoas for Reef Tanks

My FB Page: https://www.facebook.com/coralfish12g http://reefertees.com/ In this CoralFish video I am going to be giving you my list of the top 10 Zoanthids and Palythoas for reef aquariums. I tried my best to base this list of popularity, price and input I researched online. If I used one of your pictures in the video let me know in the comments so I can thank you!

HLLE and the Activated Carbon Connection

HLLE in an ocean surgeonfish (Acanthurus bahianus) caused by the use of activated carbon. Many different factors have been considered as possible causes of the disease known as Head and Lateral Line Erosion (HLLE)—a condition that typically causes disfiguring tissue erosion on the head and along the sensory lateral line of certain marine fishes. Poor water quality, nutritional deficiencies, protozoa of the genus Hexamita, stray voltage, and activated carbon use are just some of the potential causes that have been floated over the years. However, as Jay Hemdal explains in the following excerpt from his new eBook, The Salt Smart Guide to Preventing, Diagnosing, and Treating Diseases of Marine Fishes, there is now some solid scientific backing to the notion that activated carbon can cause this condition. From Chapter 3: Husbandry, Environment, and Your Fishes’ Health “A relationship between the use of activated carbon in aquariums and the development of HLLE in surgeonfish has been positively shown in two scientific studies. Other than that, no formal studies have been undertaken that identify other causes. However, a multitude of unproven causes have been presented by various people. Commonly, stray electrical currents and vitamin deficiencies are cited as causes, but one of the studies mentioned above ruled these out as common causes

Write-up Wednesday: Goldflake Angelfish (Apolemichthys xanthopunctatus)

The Goldflake Angel is one of the most striking angelfish available for a saltwater tank. Their bodies are a combination of bright and muted yellow areas with brighter spots of yellow which give the fish its name. As a juvenile, the fins are almost completely yellow with a black spot on the rear of the dorsal fin. When the fish matures into an adult the fins become black which make the fish even more striking. Add on a mouth that is purple-blue and you’ve got on eye-catching fish.

While these fish are available in smaller sizes, they can grow up to 10” (25 cm) as an adult which means they’ll need a lot of swimming space. Goldflakes will do best in tanks sized 150 gallons (567 L)or better. Please do not be fooled into thinking that a small specimen is a dwarf angel and will do well in a small tank.

Like most angelfish, Goldflakes are definitely “fish in the fringe” as they can develop tastes for corals. Adding to the risk is the fact that you won’t know if the fish nips or eats corals until you place the fish in your tank. My Goldflake Angel is a model citizen and ignores all coral. I’m fully aware the fish’s taste could change and I’m ok with that fact. If you love your coral more than your fish, or you don’t want to risk having to remove the fish from your tank, the Goldflake Angel is not for you.

AquaNerd’s Top 10 Stories from 2014

Phew…2014 is almost over. And while it has been a fun year, it has also been an exhausting one. But, we made it, and we can look forward to the brand new adventures that await for us in 2015. Before we can move on, however, we must pay our respects to the passing year with a robust recap of the top 10 stories that were featured on the AquaNerd Blog during that time. So, without further adieu, here is our list of posts we got the most mileage out of.

Review: Maxspect XF150 Gyre Generator

Following on from our recent unboxing review in which we covered the basics of this unit, we’ve now had the XF150 running on our test tank for a few weeks so we thought we’d share out observations of this product in a full operational review. We’ve also been monitoring discussions on various forums with interest and we’ll aim to specifically discus some of the points raised with our own direct experience. Firstly, the XF150 is easy to install but it’s worth familiarising yourself fully with the operation of the device before sticking it straight in the tank. Although the unit comes in a single piece you will need to reassemble it if you are wanting to use it for anything other than constant one way gyre generation as the different rotors and cages will need to be fitted. It’s certainly worth running through this process anyway actually as being familiar with the principle behind the equipment’s operation will likely mean you get more out of it

Perfect Aquarium Nerd Christmas Gifts 2014 Edition

With Christmas about three weeks away and closing in fast, we’ve decided to compile our annual list of aquarium goodies that you can get the aquarium nerd in your life. This is a diverse list that represents different price points and different types of gear. Of course, this list isn’t all inclusive, but we tried to represent the most popular and most useful products available.

6 Comments Non-Hobbyists Make When Viewing Marine Aquariums

The other day, two installers were in my home laying a new vinyl floor in my kitchen when they took note of my aquariums. One of them was especially enthralled by my reef tank (which is ironic—more on this later) and asked about a dozen questions. He even took out his phone and snapped a picture of the tank to show his wife. It’s always interesting to hear non-hobbyists’ reactions to my aquariums because they’re surprisingly consistent and, I suspect, give a pretty good sense of how most non-salties perceive our avocation. Here are just a few of the more common questions and comments I hear. Perhaps some will sound familiar to you. 1) “Is that a freshwater or saltwater tank?” Now, I’ve been asked this question aplenty, but it still surprises me a little bit every time.
