. A balanced marine aquarium / Barbara Jayne Palko. The biology of marine aquarium fishes collected in Marine [ Monroe] County, Florida / Deb Hess and John Stevely. Marine Fish living on the bottom are probably the most popular; good choices would be found among the various species of jawfish and worm gobies. A 30-gallon tank can handle up to six. Jawfish are a good choice, add activity to any tank, have been known to spawn in a community tank, and are all hardy and good feeders. The most important consideration for jawfish is the bottom substrate. Jawfish and worm gobies need shells or coral pieces to structure holes in the bottom of the tank. If you use a "soft" media, such as the finely crushed coral sold commercially, then you must provide them with some decorative clam shells or flat rocks to hide under. If jawfish are unhappy with their "home" they will go to the surface and look for a way out of the tank. They usually succeed, too - much to your distress! Bottom dwellers are also notorious for rearranging an aquarium, moving bottom media, shells, plants, etc., to suit their desires. If you don't want your aquarium rearranged regularly, do not put jawfish, worm gobies, or other bottom dwellers in your system. Use hermit crabs and brittle starfish instead. Rock dwellers are also good and possibilities include neon gobies, other gobies, basslets, clinnids, hawkfish, and blennies. The neon goby is a cleaner fish and a pair can be both attractive and functional. They will establish a cleaning station, much as in nature, and have been known to spawn in a closed system. Another choice is the basslets, including the royal grammas (Gramma loreto) and the blackcap basslets (G. melacara). 16.
