As said, Gobies live in all forms of water. During spawning, the female Goby attach their eggs to any under-water item, which are then guarded by the male.
Peacock Goby (Tateurndina ocellicauda) is an attractive, peaceful fish and can tolerate most tap-water. In Papua New Guinea they grow to 5cm (2") however mine were less than 2.5cm (1"). The females have a plumper belly than the male and breeding can be done in a small tank. Males guard the eggs and occasionally when the young starting to swim.
