Review: Prodibio BioKit Reef

MG 2674 300x274 Review: Prodibio BioKit ReefHaving set-up and managed several different reef aquaria over the last decade or so, we’ve used quite a few different biological methodologies and employed a range of different technology in the quest for the best possible conditions for our stock. In that period we’ve seen companies, and the approaches they tout, rise and sometimes fall away into obscurity. The use of probiotic supplements to attain low nutrient levels in reefs is an approach that has gained popularity in recent years and now appears to have become firmly established as a viable methodology for the long term maintenance of reef aquaria. Furthermore, this method is clearly capable of producing some of the most visually stunning aquaria, particularly SPS dominated systems. Given this, and the fact that our own test system had reached a point suitable for the deployment of such a method, we decided to conduct our own foray into the world of probiotics.  After several weeks of research MORE

Overview of Sponges

Futuyma 2009 293x300 Overview of Sponges

Source: Futuyma, 2009

 Although commonly regarded as the most primitive multicellular animal group, sponges – members of the phylum: Porifera, are both diverse and interesting. Currently, this phylum is described as consisting almost completely of 3 distinct classes: Demospongea, Calcarea, and Hexactinellida. Roughly 95% of living sponge species fall into the class: Demospongea. This group of sponges has spicules – small skeletal structures that are composed of spongin – a soft, spongy protein, and/or SiO2 – the solid chemical compound that forms glass and quartz. If you see a “spongy-looking” creature in your reef aquarium, chances are it is a Demosponge.

 The next group, Calcarea, is thought to include around 3% of living sponge species. This group features sponges that have a skeleton composed of rigid MORE

Captive Bred Heniochus Butterflyfish – We’re “THIS CLOSE”!

893cthis close Captive Bred Heniochus Butterflyfish – We’re “THIS CLOSE”!How close are we? “This Close”! It occurred to me that sometimes we use the phrase “this close” in idle conversation, often holding up our fingers perhaps a centimeter apart, as if to give an actual indication of dimension when what we’re really trying to convey is is not something so physically concrete. Instead, we’re talking about missing the mark by “that much”, 9/10ths of the way, the slimmest of margins. We’re talking about a cry from the back seat, demanding to know “are we there yet?” with 10 minutes left on the car ride. In other words, “This Close” might be something best summed up as simply a goal not met, an accomplishment narrowly avoided, also known as hearbreaking disappointment, but on the edge of greatness all the same. Or my personal favorite twist on a classic phrase, “snatching defeat from the jaws of victory” (yes you read that correctly)! The recent butterflyfish larviculture accomplishments by Frank Baensch & the Hawaii Larval Fish Project are nothing short of groundbreaking, but a captive-bred Butterflyfish is not here just yet. MORE: Captive Bred Heniochus Butterflyfish – We’re “THIS CLOSE”!

Candy Bass, Candy Basslet, Liopropoma carmabi

452aCandy 1 457x305 Candy Bass, Candy Basslet, Liopropoma carmabiGood morning gang, here is one of the hands down most beautiful fish in the Caribbean and sadly no diver will ever get to see it!! This colorful beauty is called a Candy Basslet, Liopropoma carmabi and lives at around 225 feet!! This is considered a Sea Bass in the Serranidae family and only grows to be about two inches in length! As you can see, these mini sea bass are boldly marked with stripes generally in shades of light brown to red-brown or yellow-brown alternating with red to maroon but stripes may be occasionally yellow to lavender or even blue as you see here!! They typically inhabit deep coral reefs and rubble slopes and are very reclusive and will remain hidden inside recesses until danger passes MORE

Dinoflagellates, how to solve the problem with Fauna Marin Ultra AlgeaX

image Dinoflagellates, how to solve the problem with Fauna Marin Ultra AlgeaXThe dinoflagellates in the aquarium are a problem to be reckoned with, I did it and what you see above is the result… but how can you intervene in a case like this? The dinoflagellates are extremely small, almost microscopic, algae, equipped with flagellates, prone to reproduce themselves in an extremely fast. My infestation comes from far away, but with the previous LED ceiling light, the Sicce GNC AM466, after several months, it seemed that the problem had almost disappeared, while the transition to the new ceiling, the Ecotech Marine Radion XR30w, the problem has come back stronger than ever. At first I tried to keep the dKh high MORE

Astreopora and Cyphastrea—So Similar, Yet Different

Astreopora Cyphastrea1 300x187 Astreopora and Cyphastrea—So Similar, Yet DifferentA few years ago, if you asked me about Astreopora or Cyphastrea, I probably would not have a whole lot to contribute to the discussion. They were (and still are to a large degree) some of the most rare corals imported and seldom seen in stores. I still remember the first time I saw a “Meteor Shower” Cyphastrea and was blown away by its incredible contrast of red and blue. Over the years, more and more color morphs made their way stateside and, thankfully, people started propagating them. They are similar… On our website, we try our best to separate corals into their respective categories to make it easier to shop for stuff, and occasionally we run into close calls like Cyphastrea and Astreopora that are sometimes really difficult to tell apart. Obviously, their appearance is similar. They have small polyps that grow out from a web-like, textured coenosteum (calcareous skeleton). More: Astreopora and Cyphastrea—So Similar, Yet Different
