While there are fresh and brackish water goby species they are not usually as many as the marine water variety. It is interesting though to note that the fresh water varieties of goby fish are usually well adapted for a wide range of habitats including the captive habitat.
It was not until recently that the fresh water varieties of the goby fish were discovered and finally introduced into the aquarium hobby. The gobies generally have tapered bodies with big heads although they have relatively small bodies.
A large percentage of fish from the goby family exhibit pelvic fins that are fused thus forming a structure beneath them that look like a suction cup.
Interestingly, it is this suction cup-like structure that the fish typically use to attach itself to rocks in the ocean to avoid being swept away by the currents in the ocean. Due to the many different varieties of the goby fish species that exist, it is difficult to categorically give a definite definition of each of the fish appearance. Much of such description will mostly just be generalist to help give the reader a general idea of what the fish is like.
The fish general inhabit the coast mostly in tropical and warmer temperate regions. A big percentage of the fish are marine inhabitants but there are also other varieties that inhabit fresh and brackish waters. The gobies are known to exist in different parts of the world including East Asia, the Pacific Ocean and even the Americas. Gobies are usually very small fish and will not grow long therefore you will not need to have a very large tank.
A small tank will readily do as long as you have kept the tank requirements as advised by experts. Another good characteristic of the fish is that they are hardy and will survive in a variety of conditions but this is not supposed to be taken for offering them poor care.
When they are properly taken care of, the fish have the capability of living up to ten years long! For an up-close of the tank requirements for the Goby Fish and general care please continue reading below to find out more:.
Why are round gobies a problem? The round goby can displace native fish from prime habitat and spawning areas. Round gobies eat the eggs and young of other fish species. Have a competitive advantage over other species because of the ability to survive in poor quality water. How do round gobies spread?

Round goby What you need to know about the round goby. On this page Skip this page navigation. Round Goby Neogobius melanostomus The round goby is a small, bottom-dwelling invasive fish. Range Outside its native range, the round goby has been found in all five Great Lakes and many of their tributaries.
The fish compete with and prey on native bottom-dwelling fish such as mottled sculpin Cottus bairdii and logperch Percina caprodes. Round goby also threaten several species at risk in the Great Lakes Basin, including the northern madtom Noturus stigmosus , the eastern sand darter Ammocrypta pellucida , and several species of freshwater mussels.
Round goby have reduced populations of sport fish by eating their eggs and young, and competing for food sources. Researchers believe the round goby is linked to outbreaks of botulism type E in Great Lakes fish and fish- eating birds. The disease is caused by a toxin that may be passed from zebra mussels, to goby, to birds, resulting in large die-offs of fish and birds. Small, bottom-dwelling round goby.
