Here in the US, the summer travel season is well underway, and popular attractions all across the nation are swarming with tourists. For those of us enamored with marine life, vacation travel often involves a visit to major public aquariums,…

Threadfin Cardinalfish: Peaceful and Most Impressive in Numbers

Walk by an LFS sales tank containing a few specimens of threadfin cardinalfish (Zoramia leptacantha), and you might not give them a second glance. Chromatically speaking, this species isn’t exactly a showstopper compared to some, especially when viewed in your…

Specialized Care is Key to Success with Sun Corals

When ascribed to the various species of the genus Tubastraea, the common name “sun coral” is both fitting and ironic. It’s fitting when you consider that the spectacular polyps of many Tubastraea species can quite justifiably be described as sun-like…

Rock Beauty Angelfish: a Finicky Feeder Best Left in the Sea

On one of my earliest dives down in the Florida Keys back in the 1990s, a gorgeous yellow and black angelfish caught my attention as I drifted over a section of reef. In my mind’s eye, I envision the angel…

Tridacna derasa: A Good Excuse to Clam Up!

Beginners: Never Add Livestock to Your Marine Aquarium under These 5 Circumstances

The Hammer Coral: A Sizeable Stinger with Showpiece Potential

Several of the so-called large-polyp stony (LPS) corals offer the advantages of being very hardy, adaptable, and beautiful and, thus, make excellent reef aquarium candidates, even for relatively new reefkeepers. The hammer coral (Euphyllia ancora), however, I would characterize slightly…

The Yellow Clown Goby: A Practically Perfect Nano Candidate

Nano marine aquarium enthusiasts must be very discerning in their livestock selections to ensure any specimens they choose won’t outgrow their systems. Reaching a maximum size that can best be described as miniscule, the yellow clown goby (Gobiodon okinawae) is…
