The Pacific Sailfin Tang: A Hardy, Bold Species Demanding Spacious Accommodations

The Pacific sailfin tang (Zebrasoma velifer), not to be confused with its Red Sea namesake (Zebrasoma desjardinii), is a fish with many attributes that make it desirable to marine aquarium hobbyists—it’s attractive, hardy, bold, easy to feed, etc. But don’t…

The Iconic Raccoon Butterflyfish

Some of the marine fish we like to keep are surprisingly recognizable to both hobbyists and non-hobbyists alike—probably because they’re frequently depicted in photographs and artwork. Among these iconic fishes is the raccoon butterflyfish (Chaetodon lunula) of the Indo-Pacific and…

The Two-Stripe Damsel: Hardiness and Hostility in Equal Measure

Among the pomacentrids (damsels and clownfishes) are many species that rank exceptionally high when it comes to hardiness in aquaria (thus their once common use as tank cyclers) but also tend to mature into little hellions that can turn a…

The Pyramid Butterflyfish: A Hardy, Reef-Safe Chaetodontid

Don’t Get Burned by Flame Scallops!

Mention beautiful bivalves for the marine aquarium, and the various tridacnid clams (the so-called giant clams) will probably come to mind. Likely, the flame scallops of the genus Ctenoides will too. However, while the tridacnids have a fairly decent survival…

Chaetodon kleinii: An Excellent Beginner’s Butterflyfish

The word “beginner” and “butterflyfish” aren’t often paired together, as so many of the butterflyfishes seem to present some manner of husbandry challenge, often related to diet. Still, certain butterflies have a well-deserved reputation for hardiness and general ease of…

Humbug Damsel: Prepping for the Hunt

There’s a reason I chose to spotlight Dascyllus aruanus, the humbug or three-striped damselfish, in this profile. “Caribbean” Chris and I will soon be matching wits with four representatives of this species that have laid claim to a large marine…
