consider that there are over 2000 known species of go-bies,most of them marine,but less than a dozen are reared on a commercial scale.most of them would prove just as easy as the first,and the only reason they haven't been captive-bred is that no one has tried.inspired?be observant and watch fish at local pet shops.look for possible signs of courtship,research the species' requirements,set up some aquariums and raise them.be the first to bring a new species through spawning and rearing in captivity.marine aquarists of the future will be indebted to you.
