This beautiful nano fish displays bright neon blue coloration in males, is very peaceful with dwarf shrimp, and is very hardy in a mature aquarium that is rich in algae and biofilm.
***PLEASE NOTE: There are many goby species that are sold as "Neon Blue Goby" and other similar descriptions. The species in this listing, the TRUE Stiphodon atropurpureus, is very rare and seldom available.
The Electric Blue Neon Dwarf Goby (Stiphodon atropurpureus) is a very rare freshwater dwarf goby that is native to Japan, Taiwan, and Micronesia. It is known for the bright neon blue color that male (and, to a lesser degree, some female) specimens display. Females are not as colorful, but are still very attractively marked with horizontal black and cream-colored stripes. This fascinating, peaceful fish is an algae and biofilm grazer that is an excellent candidate for the mature nano aquarium.
An aquarium with heavy water flow (10-15x turnover per hour) and very clean, clear water is required for the Electric Blue Neon Dwarf Goby. This fish is native to shallow, clear, fast-flowing waters and it is sensitive to declines in water quality, so regular aquarium maintenance is a must.
The Electric Blue Neon Dwarf Goby is a biofilm and algae grazer in nature. It is known to usually accept frozen meaty foods, but such foods should only be fed occasionally. This fish will also sometimes accept high-quality dry foods that are rich in plant matter, but it is absolutely essential that biofilm and algae are naturally available in the aquarium to ensure its long-term health or else it may slowly starve. As long as it is kept in a well-maintained, mature aquarium with good biofilm and algae growth as well as high water flow, the Blue Neon Dwarf Goby is a hardy and entertaining fish. It will not bother aquarium plants. In fact, Anubias species are an excellent plant to keep with this goby because Anubias can foster significant biofilm/algae growth in an aquarium with moderate to high lighting.
Most small rasboras, tetras, hillstream loaches, and other small, peaceful fish are good tankmates for the Electric Blue Neon Dwarf Goby. Due to its small size and diet, the Electric Blue Neon Dwarf Goby can also be kept with dwarf shrimp, although it might eat a few of their fry. Dwarf shrimp are particularly good tankmates in larger aquariums where they can find areas of lower water flow. Peaceful bottom-dwelling fish are also a possibility, but care must be taken to make sure that the passive Blue Neon Dwarf Goby is not outcompeted for food. Female Electric Blue Neon Dwarf Gobies will often congregate together, even with other goby species such as the Gold Neon Dwarf Goby. Males seem to be able to differentiate between females of different species during courtship behavior.
There are reported cases of the Electric Blue Neon Dwarf Goby spawning in the aquarium, but it is very difficult (if not currently impossible) to raise the fry due to their complex larval stages. In nature, adults spawn and their fry hatch in freshwater, then they are immediately swept downstream to marine ocean waters where they feed and develop. As the fry mature, they swim great distances back to full freshwater streams, often on completely different islands than where they originated. At this point, the fry have become young adults are will soon be sexually mature and exhibit adult coloration.
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.
