The Apogee MQ-200 Quantum Meter offers many advantages to aquarium hobbyists. The meter is relatively inexpensive (as quantum meters go) and the submersible sensor is small and allows measurements to be made in tight spots. Hobbyists should take a careful look and see if this PAR meter is for them.
Australia is home to the the world's most famous natural coral reef. It's also home to some pretty incredible captive reefs. We present vpreef's (John D's) outstanding aquarium. At less than a year old, it's already a real showstopper.
Can we possibly match the amount of natural light in an aquarium?
I'll provide you information about the genus Siganus as a whole, the Rabbitfish species commonly offered in the hobby, and how to take good care of them.
Equipment Review: LED Lighting Tests: Ecotech Radion Pro, Aqua Illumination Hydra, GHL Mitras 6100HV and 6200HV
LED lighting has come a long way and the new generation of LED fixtures is delivering on the promise of LED technology, and control features. As usual, the users need to consider their own applications to determine the best one for the situation. Hopefully this data will be helpful in making your decisions.
Our very own Editor in Chief, Terry Siegel discusses surgeonfish husbandry like only he can – through forty years of personal experiences successfully keeping this beloved family of fish.
Crinoids are rather elegant relatives of the brittle stars, sea stars, and sea urchins, and can be quite spectacular in appearance. You might see them offered for sale at times, but as pretty as they may be their survival record in home aquariums is downright dismal. However, they're interesting invertebrate animals nonetheless, so I'll give you some information about them, and will also cover the reasons they typically do not survive long-term in home aquariums.
Richard Aspinall concludes his exploration of The Deep Aquarium in Hull (UK), with a look at the Deep's conservation and education work.
Advanced Aquarist welcomes Francesco Ricciardi, a biologist and underwater photographer. Francesco shares his photography and presents an overview of tropical butterflyfish.
Continuing in the same vein as my previous LED lighting tests, this article presents data on light intensity and spread along with spectral plots for several new LED fixtures.
These are my favorite invertebrates, and with a little planning and preparation can be fantastic acquisitions for any marine aquarist. In fact, after writing this, I feel a compulsion to go get another one...
In the first of a two part investigation, Richard Aspinall has a behind the scenes tour of The Deep in Hull, one of Europe’s largest and most well respected public aquariums.
The mutualistic symbiosis between corals and zooxanthellae is a well-known fact amongst aquarists. To improve our understanding of zooxanthellae biology, scientists isolate these symbionts from the coral host under a variety of environmental conditions. This article will provide an overview of zooxanthellae biology, and how these dinoflagellates are isolated for scientific study. This will give aquarists more insight into, and hopefully appreciation for, the symbiosis between zooxanthellae and the corals they grow in their home aquaria.
Conventional reefkeeping wisdom says live corals should not coexist with big angelfish and butterflyfish. Don't tell that Bryn Roberts. With careful selection of fish, corals, and invertebrates, Bryn pushes the boundaries of "reef safe." Large, colorful coral colonies thrive in the presence of rare angels and butterflies.
There are several species of giant clam available to us, all of which belong to the family Tridacnidae, with each being unique in its own ways. Of these, Tridacna squamosa, is one of the hardiest and easiest to care for, and can be one of the most attractive, too. So, this month I'll give you some information about T. squamosa, which is commonly called the squamosa clam, scaly clam, scaled giant clam, or fluted clam.
