World’s Smallest Aquarium in HD

Posted on Friday, February 25th, 2011 at 5:05 pm

Anatoly Konenko created the a glass aquarium measuring 30 x 24 x 14 mm. The tiny little tank contains miniature plants, rocks, and a couple of fish. Now…what was that fish-per-gallon ratio again? So let’s see…this plus that, carry the one, nevermind!

Although clearly (read hopefully!) not a long-term project, the tank uses a an air pump to ensure there is some oxygen exchange. You have to admit that water changes are going to be quite easy, although maintaining salinity and temperature, pretty much impossible.

Again, we hope this was just made and shot as a cool little video, and fish were then moved to an acceptable tank.

Skimz TurbMagnum ST600

Posted on Friday, February 25th, 2011 at 4:47 pm

The commercial sized recirculating Skimz TurbMagnum ST600 is designed for nano tank up to 20 gallons. Ok fine, it’s designed for commercial farms, large public aquariums and other large aquatic setups. The newly developed Hybrid Needlewheel Impleller (HNI) increases the air intake, and makes this skimmer extremely efficient. This large protein skimmer uses a bubble plate to reduce turbulence inside the reaction chamber. Producing an absurd amount of fine bubbles, the TurbMagnum ST600 is an absolute beast.

This large commercial skimmer comes with a Self Waching Head (SWH), which Skimz claims increases efficiency by up to 30%. The SWH washes away accumulated skimmate on the riser neck and allows the unit to optimally perform at all times with minimum maintenance. The skimmer is powered by two Reeflow HammerHead pumps, and has a quick release valve for flushing out the chamber.

Red Sea Salt and Coral Pro Salt

Posted on Friday, February 25th, 2011 at 2:18 pm

Red Sea’s new Red Sea and Coral Pro salts are now produced using new formulas. With “it’s all in the balance” as their new tagline for this salt line, Red Sea is pushing the idea of optimal balance between Calcium Carbonates, and Magnesium (Foundation Elements). As we all know, it’s this balance (along with other things) that contribute to coral growth and vitality. If the salt you use mixes to the exact parameters you’re trying to keep, then you need not add anything to the fresh saltwater mix when doing waterchanges.

Red Sea Salt
The all new formula provides the exact parameters of tropical reef water with a slightly elevated alkalinity as needed in a closed marind system. Red Sea salt is ideal for fish and invertebrate systems, mature or low-nutrient SPS tanks.

Red Sea Coral Pro Salt
Contains elevated leveland of the foundation elements necessary for sustainable, accelerated coral growth. Coral Pro salt is ideal for reef aquariums, in particular for LPS and SPS corals and growing out coral frags

Both salt mixes use over 72% Sodium Chloride (NaCl) harvested from the Red Sea itself, capturing 45 trace elements found in natural reef waters.

Marine Life Disguise Techniques

Posted on Friday, February 25th, 2011 at 11:13 am

In a recent Coral Magazine email, we saw this great BBC video we thought you’d like. The video is titled “Underwater masters of disguise – Wild Indonesia” depicts disguises which have been adopted by many forms of marine life in order to avoid predators. You’ll be amazed at the warning and deception abilities of frogfish, pipefish, seahorses, sand-skimming flounders, and many more species.

An example we normally see in our tanks, are the clownfish who “steal” a chemical from host anemones, so that the anemone doesn’t recognize them as prey. It’s amazing that cardinalfish and hawkfish are starting to develop the same abilities, and as this video show, are now living within anemones in the wild. Just another example of evolution taking it’s course.

Blue Eyed Crab

Posted on Monday, February 21st, 2011 at 5:45 pm

How could this cute little crab with the pretty blue eyes be so mean? Meet Cymo spp. eater of Acroporas and other prized SPS corals. These crabs are about the same size as beneficial Tetralia spp. crabs and are often mistaken for “good” crabs. The differences? Blue Eyed crabs are hairy, not smooth like Acropora guard crabs, and as the name suggests, they often have blue eyes. The eye color can sometimes be more whitish or washed out, especially in smaller individuals.

It’s not easy to see this small crab in an SPS colony, and usually the path of destruction is visible first. If you find off-white skeleton starting more at the base of your SPS colony, look for one of these bad crabs. You’ll likely find it at the edge of its methodically destroyed white patch picking coral tissue with its claws and shoving the healthy tissue into its evil little mouth.

Removal is just as difficult as any other unwanted crab in a reef tank. I find a pointed metal or bamboo skewer works best. It’s easiest if you can pick up the colony and chase the little crab around, poking its underside with a thin, pointed object like the inside of a ballpoint pen until it lets go with its legs and bails out.

The Cymo andreossyi from Singapore, an eater of Acropora and Pocillopora corals, is listed as Vulnerable on the IUCN, but the others are common and often come as hitchhikers on wild caught coral colonies.
