Naso lituratus: a Sleek, Striking, Outstanding Fish for Spacious Marine Aquariums
Certain marine fish really make me wish I could afford to set up and maintain a much larger aquarium. Among these is Naso lituratus, the lipstick tang, aka the naso tang, tricolor tang, or orangespine unicornfish. Alas, this hardy, attractive…
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…
