The Yellow Lycopod / Dusky Brotulid
The Yellow Lycopod is the rarer color morph of an already rare fish known as the Dusky Brotulid, which hails from the tropical Indo-Pacific. They are small fish growing only to about 7 cm (less than 3 inches). Lycopods are very reclusive and don't see well (or perhaps at all) which can make them tricky to feed. As such, they are good candidates for small tanks with other fish that are not aggressive feeders.
