About the Cover

With its distinct color pattern, the Picasso triggerfish (Rinecanthus aculaetus) is one of the most immediately identifiable marines available in the hobby. Also called the lagoon or blackbar triggerfish, this striking species is renowned for its hardiness, exquisite beauty, and territoriality. While R. aculeatus can be placed in a community tank, it should only be housed with similarly large and feisty species, such as groupers, pufferfish, tangs, and rabbitfish. It is also an ideal marine to keep in a single-species tank (p. 54), provided all specimens are roughly the same size and introduced to the tank at the same time.

Species Profiles

Tip of the Month:

That while most fish are either freshwater or marine, with a small number of species regularly inhabiting brackish estuarine habitats, a few fishes are at home in water of any salinity, including hypersaline - saltier than seawater! Some of these species, like the bull shark Carcharhinus leucas, are not potential aquarium specimens, but the group includes the popular sailfin molly Poecilla spp. and the much underappreciated native American sheepshead minnow Cyprinodon variegatus. These can be kept under fresh, brackish, or marine conditions.
