About the Cover

The cardinalfish (Apogon imberbis), also known as “king of the mullets,” belongs to the family Apogonidae of the order Perciformes and is commonly found in the Mediterranean Sea and the eastern Atlantic coast. The species pictured on the cover—along with all other species of cardinalfish—is a paternal mouthbrooder. A nocturnal species, A. imberbis are good shoaling fish to include in a temporally partitioned marine tank (p. 84) but require caves and crevices in which to rest during the day.

Tip of the Month:

Unless you have very soft water, you will eventually have to deal with "lime" buildup. When water evaporates, dissolved minerals are left behind as a white film or crust. A razor blade can remove much of the deposit, but this will scratch plastic badly. An easier and dust-free method for glass, plastic, or any other surface is to use a scrubbing pad dampened with household vinegar. The dilute acid quickly dissolves the minerals, and a thorough rinse removes any remaining vinegar.
