The Blue Neon Goby Stiphodon atropurpureus male exhibits a greyish or black base body color and a bright blue to greenish lateral stripe (which in dominant or breeding individuals can appear almost whiteish). Females have lighter base body coloration and have a dark, zig-zag like lateral stripe. Both males and females’ bodies, snouts and cheeks are iridescent.
In nature, these Gobies live in streams and mainly feed on epiphyte and biofilm on rocks in the wild.
Hobbyists should try to replicate this environment in their home aquarium with a rocky bed bottom and high aeration and strong water movement. A fast-moving, oxygen-rich environment can be achieved through the use of powerheads. Make sure the airline tubing connected to the powerhead inlet is drawing in fresh air. The use of a slightly oversized filter will also increase filtration and water movement. Care should be taken to avoid high water temperatures to ensure greater dissolved oxygen content. A tight-fitting lid or canopy is recommended to prevent escape.
Males can become aggressive with each other, so supply hiding places with rocks, boulders, or older driftwood (new pieces can leach tannins into the water and discolor it). They also like to dig, so create a base substrate of gravel, sand, or a mixture of both.
Blue Neon Gobies can be kept in a community freshwater tank with other small aquaria with peaceful temperaments and similar water requirements.
Omnivores, Red Tailed Gobies do perform beneficial foraging services, but supplement their diet with foods that sink to the bottom of the aquarium such as a high-quality flake food, sinking carnivore pellets and sinking algae wafers.
A smaller fish, these Gobies are 2” or smaller at maturity.
Approximate purchase size: 1 1/4” to 1 1/2”
