Blue Gudgeon Goby Ptereleotris heteroptera

The Blue Gudgeon Goby (Ptereleotris heteroptera) is an active marine fish that brings constant movement to a saltwater aquarium. Rather than staying close to the substrate, this species spends much of its day swimming through the water column and exploring open areas of the tank. Its elongated body and pale blue coloration give it a sleek appearance that stands out without overwhelming the display. The Blue Gudgeon Goby generally coexists well with other peaceful tankmates and is often selected by hobbyists looking to add activity and visual interest to an established reef aquarium.
