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.
Dana provides a very in-dept look at the Tunze Nanostream pumps, their flow characteristics, and water velocities and compares them to various water velocity zones found on reefs.
Stingrays of the genus Potamotrygon can be stunning aquarium animals. While they have a much better record of captive survivability than other batoids, their husbandry is hardly undemanding or uncomplicated. In actual fact, properly caring for these unusual creatures requires a considerable amount of preparation and resources.
Overall toadstools are attractive, hardy, and easy to propagate, making it easy to see why they are a long-time hobby favorite.
"I want a reliable lighting device and Build My LED seems to have hit the right note." Dana evaluates the construction, performance, and customer service of a custom-configured LED light from the new company, Build My LED.
Richard Aspinall travels to Mauritius to photograph Amphiprion chrysogaster, the exotic and beautiful Mauritian Clownfish.
While not a panacea or miracle drug, chloroquine is experiencing resurgence in popularity for use in fish-only aquariums and quarantine systems to treat a variety of problems ranging from Cryptocaryon to Aiptasia anemone infestations.
