A Pint-Sized, Potentially Picky Lionfish: Dendrochirus biocellatus

Yearn to keep a lionfish but don’t think you have the tank space to accommodate one? You might want to think again! While having a small to medium-sized tank might preclude keeping some of the popular Pterois species, there are…

A Hawkfish Even “Caribbean Chris” Could Love

Regular Saltwater Smarts visitors know that “Caribbean Chris” has an irrational (bordering on pathological) hatred of all marine life not connected in some way to the Caribbean Sea or tropical western Atlantic. By logical extension, most of the hawkfishes, being…

Panther Grouper: The Tankbuster “Poster Fish”

Every time I need to make a point about marine fish that are sold as small, cute juveniles but grow into real behemoths, the panther grouper (Cromileptes altivelis according to Fishbase/Chromileptes altivelis according to ITIS) is one of several species…

The Horned Bannerfish: Little Color but Lots of Character

When choosing fish species for our marine aquariums, bright coloration is often a highly sought-after characteristic. But there’s also something to be said for species with more subdued coloration that just happen to have really interesting morphology. One such species…

Sweet Coral Hind! A Colorful, Aquarium-Sized Grouper

The name “grouper” conjures up images of underwater behemoths that no home aquarium can conceivably accommodate, such as the legendary goliath grouper (Epinephelus itajara). Fortunately, marine aquarium hobbyists who have a yen for these hefty predators can find several attractive,…

Go Ahead and Buy a (Captive-Bred) Banggai Cardinalfish!

Being fascinating to behold, very hardy and adaptable to aquarium fare, an exceptional choice for reef systems, suitable for modest-sized aquariums, and even easy to breed in captivity, the Banggai, or Kaudern’s, cardinalfish (Pterapogon kauderni) is a lot like Mary…

Orchid Dottyback: Hardy, Peaceful, and Just Right for Reef Tanks

Captive breeding of marine fishes has been a boon to our hobby in any number of ways, one of which is democratizing access to formerly really pricy species such as the orchid dottyback (Pseudochromis fridmani). While I wouldn’t characterize the…

Fish or Fishes? Shoal or School? A Few Fishy Terms Defined

In my nearly two decades as an aquarium writer and editor, I’ve noticed that certain terms routinely used in hobby literature when discussing our fine, finny friends are often a source of confusion to readers. So for today’s post, I…

The Sturdy but Shy Marine Betta

With its dark-brown body covered with a myriad of tiny white to pale-blue dots, the marine betta, a.k.a comet (Calloplesiops altivelis) is truly a dazzling sight to behold. Start out with a healthy specimen, and you’ll find it’s also a…
