The Spotfin Goby is an often colorful, short-bodied goby species that inhabits fresh and brackish waterways, and is not often seen in the aquarium hobby!
The Spotfin Goby (Redigobius chrysosoma) is an interesting little goby species that is native to Australia, Indonesia, Papua New Guinea, and the Philippines. It inhabits streams and mangrove areas in nature. This fascinating, peaceful fish is a micropredator that is an excellent candidate for the mature nano or planted aquarium.
The Spotfin Goby is a micropredator in nature. It is known to accept frozen and live meaty foods of appropriate size. This fish usually might not accept dry foods, at least initially. As long as it is kept in a well-maintained, mature aquarium, the Spotfin Goby is a hardy and entertaining fish. It will not bother aquarium plants. In fact, Anubias species and Java Fern are excellent plants to keep with this goby.
Most small rasboras, tetras, hillstream loaches, and other small, peaceful fish are good tankmates for the Spotfin Goby. Due to its small size, it can be kept with most other peaceful fish and peaceful invertebrates that are too large to be considered prey. Peaceful bottom-dwelling fish are also a possibility in a large enough tank, but care must be taken to ensure that the Spotfin Goby is not outcompeted for food. The Spotfin Goby can be somewhat territorial, especially in smaller tanks, so it may occasionally bully other passive, slow-moving bottom-dwellers if space is limited.
Many gobies have the ability to climb glass and jump out of the water, so an aquarium lid is necessary to prevent escape.
Our young adult specimens are in excellent health, but many of the males are not yet showing their full mature coloration. This color will be most vivid when the fish are kept in a group containing both males and females.
