The Digital Reefs Black Tank – Passing 18 Months

IMG 2776web The Digital Reefs Black Tank – Passing 18 Months
As an update to the feature on our test tank in issue 43 of UltraMarine magazine way back in December 2013, we thought it was high time we put together another of our ‘black tank updates’ as the system has also recently passed the minor milestone of 18 months old. Plenty has happened since we wrote that update for UltraMarine, let alone over the last 12 months since our last update on here, so let’s dive right in before anything else happens! OK, so in terms of equipment, without doubt the biggest change has been the installation of a new acrylic sump. We made this change because we wanted to try out a new skimmer and unfortunately the water level in the original sump was too high to allow for headroom of this new model, given the water depth required. So, after having used the Hydor Performer recirculating skimmer for a few months, we’ve now got a Vertex Omega 150 running on the system. Running smoothly for several months, this skimmer sits in a More: The Digital Reefs Black Tank – Passing 18 Months.More:

Harmless or Helpful Live Rock Hitchhikers: “Pods”

pods1 Harmless or Helpful Live Rock Hitchhikers: “Pods”Regular Saltwater Smarts readers often see references to them in Paul B’s posts. They arrive in our aquaria unbidden aboard chunks of live rock, in live sand, or on coral specimens attached to rocks. At a glance, they look like little insects scurrying over the rocks or swarming on the glass. I’m talking about “pods”—not the Invasion of the Body Snatchers kind (though we haven’t ruled that out completely with Paul B.), but the tiny crustaceans known as amphipods and copepods. Amphipods The first pods we’ll discuss—amphipods—are much larger than copepods and can be seen easily with the naked eye as they scramble among the rockwork, typically after lights out (they tend to make themselves scarce during daylight hours to avoid predation). These shrimp-like microcrustaceans, which are usually somewhere in the range of 1/8 to 1/4 inch in length with the occasional “whopper” making an appearance, look rather like commas with multiple segments and lots of legs.

Review: Cubic Orbit 20 Jellyfish Aquarium

IMG 2016 300x200 Review: Cubic Orbit 20 Jellyfish Aquarium Frequently on show in specialist exhibits like public aquaria, it seems a common perception that keeping jellyfish is beyond the average individual, perhaps even if they are already marine hobbyists maintaining complex reef aquaria. Maybe it’s due to the delicate appearance of the organisms themselves, or maybe it’s the almost clinical appearance of their holding systems that makes people often think it just isn’t possible in a home setting. Over the last few years though, technology and understanding has improved and now it is entirely feasible to maintain these fascinating and mesmerising creatures in your own home as easily as any small aquarium. In this review we take a look at one such system, the Cubic Orbit 20 which is distributed in the UK by London-based specialist Glass Ocean. Having already seen positive reviews on this product we were keen to try it for ourselves and, after we contacted Glass Ocean, a few days later our system was delivered. We must commend Glass Ocean here for some superb service…. both the delivery of the systems and the packaging were top notch. The manufacturers, Cubic, are a UK-based company founded in 2010 and their personnel includes those from a public aquarium background as well as a marine biologist. The Cubic Orbit 20 itself is the smallest More: Review: Cubic Orbit 20 Jellyfish AquariumMore:

Deep Sea Octopus, Rare Octopus, Octopuses

11bf900foot Octopus 9 18 14 457x305 Deep Sea Octopus, Rare Octopus, OctopusesGood morning from the sunny Caribbean! So as promised I have a new octopus that was found by the Smithsonian Institution last friday in the “Curasub” between 900 and 1000 feet! Is this guy cool looking or what?? And again here is a mega colorful animal that lives in complete darkness so why the need to be so colorful?? As of now I don’t have a name for you and like everything new that comes up from the deep it could be a new species, that’s why we have the Worlds top scientists here to answer questions like this. How big is he you ask? MOREMore:

Larval Rearing of the Purple Masked Angelfish (Paracentropyge venusta) Using Only Cultured Food

P.%2Bvenusta%2B72414%2Bday%2B25%2Bright%2Bside%2Bprehistoric Larval Rearing of the Purple Masked Angelfish (Paracentropyge venusta) Using Only Cultured FoodOver the past year while working on our Rising Tide project, the larval rearing work has focused on the Purple Masked Angelfish Paracentropyge venusta. We had success on our fifth rearing trial in getting the larvae to the juvenile stage. That larval trial started in November of 2013 and the success was most likely brought about through the use of wild plankton collected from Kaneohe Bay. Plankton was collected almost daily in an effort to provide the larval fish with the necessary nutrients to get them through the larval phases, past metamorphosis and into the juvenile stage. Although we were happy with this accomplishment it meant that larval rearing of this species might be dependent and only possible in areas near a source of wild plankton. In an effort to make larval rearing successful in any location our next step was to try and rear the P. venusta using only cultured food items.
P.%2Bvenusta%2Bday%2B44%2B81214%2B1.6cm%2BTL%2B Larval Rearing of the Purple Masked Angelfish (Paracentropyge venusta) Using Only Cultured FoodOn our third try while using only cultured foods for the P. venusta larvae we had success again to the juvenile stage. This larval run, “Trial 8” started on June 28, 2014 and the juveniles are currently just over three months old wearing their beautiful yellow and blue colors and are fully transitioned onto frozen and flake foods.  The food items used for this trial were the calanoid copepod, Parvocalanus crassirostris, the rotifer, Brachionus plicatilis, and thebrine shrimp Artemia salina. We were pleasantly surprised that this larval run was on a faster track as compared with our successful wild plankton fed larval run which was quite long. The temperature of this run averaged 26C whereas out trial 5 temperature averaged 25C and this of course could be the reason for faster larval development. We also had a better percent survival with Trial 8 showing 20% survival at day 40 compared to trial 5 at 8.5% survival at day 40. The larvae in Trial 8 were able to capture larger prey starting at day 12 while the larvae in Trial 5 were closer to day 30 when they were able to catch larger prey. The transition to non living foods for the fish in trial 5 took place at 137 days old, which is more than six weeks longer than the fish in trial 8! So not only is it possible to rear these angelfish on only cultured foods, they actually did better on it MORE: Larval Rearing of the Purple Masked Angelfish (Paracentropyge venusta) Using Only Cultured FoodMore:
