The reproductive strategy of the invasive Gobi fish typifies the aggressiveness of lake invaders. Gobies can spawn every 20 days from April through September. Gobis displace desirable locals by eating their food and eggs. http://www.worldlakes.org/Invasive Species problems.htm
Goby is the common name for about 1500 related species
of fish found all over the world, in both fresh and salt waters. Although several tropical species live in coral
or in the cavities of living sponges, most gobies live in sand- or mud-bottom holes or burrows. During the spawning
period the female goby attaches her eggs to an underwater object; the male guards them until they have hatched.
Although classification is not fixed, gobies have been divided into a number of families.
One family, for example, consists of those species that have their pelvic fins united to form a sucking disk by
which they fasten themselves to rocks or other underwater objects, while another family contains species that have
separated pelvic fins.
