Microcosm proudly launches its all-new series of pocketexpert guide for Aquarists and Underwater Naturalists with Marine Fishes by Scott W. Michael. Designed as a quick but authoritative handbook on the 500 "need to know" fish species seen and kept by marine aquarists, this first Pocketexpert is a must-have reference for all saltwater hobbyists and professionals. Next in the Pocketexpert series will be Marine Invertebrates by Dr. Ronald Shimek (available Winter 1999/2000).
