AMUR GOBY (Feeding, Breeding and Tank Setup)

AMUR GOBY belongs to “Rhinogobius Brunneus” While the majority of the more than 2000 species of gobies are found in marine waters, there is a small percentage available to freshwater keepers. Among these, the genre of Rhinogobius stands out as several species are sometimes available to aquarists.

The Amur Goby is one of these and is perfect for unheated aquaria. There is some confusion in the R. brunneus group as the body colors and facial markings can vary widely based on location and habitat.

In addition, in some populations, the young upon hatching are washed down to the sea while others are landlocked and the young settle in still freshwater lakes or slow-moving rivers.

One paper I read for this suggested that the fully freshwater variety is actually R. flumineus, but that species is found only in Japan while the freshwater Amur Gobies range throughout northeast Asia.

Can we keep amur gobby in a home aquarium?

The ones in the photo are fully freshwater individuals from Korea. Amur gobies are easy to keep in a home aquarium and will reproduce if provided protein-rich foods.

Amur gobies must be kept in a group otherwise they become inactive and may eventually refuse to feed. You should have at least two males in the tank and several females. The males are territorial and will engage in battles that consist of opening their jaws as wide as possible and displaying their fins.

These battles are frequent and rarely lead to injury. Amur gobies are smaller than some of their relatives and a small group can be comfortably kept in a 20 gallon/70 liter tank.

Feeding:

Give these fish live or frozen food. Some may learn to eat pellets, but many never recognize that as food. They prefer bloodworms, blackworms, chopped earthworms, mosquito larvae, and other aquatic insects and crustaceans.

Habitat:

Their tank can have a sand or gravel substrate and should contain many stones. The stones should be arranged to create caves and overhangs which could be utilized in spawning. The water should have a good current but not as fast as hillstream conditions. The water should be well-oxygenated.

Breeding:

The males displays at the mouth of his cave. The female enters to deposit the eggs and then leaves the male who protects and fans the eggs. Studies have shown it is not beneficial to have two males present at this time.

Although they can still spawn when more than one male is in the tank, the survival rate of the eggs and fry are lower as the male spends less time fanning his brood.
