About Helfrichi Firefish

The Helfrichi Firefish is the most colorful and sought-after firefish species, featuring a stunning combination of yellow head, purple body, and dramatic elongated dorsal fins. Native to deep waters of the Indo-Pacific, these rare fish command high prices due to collection depth and limited availability. They are peaceful but extremely shy and require pristine water conditions. Like all firefish, they are notorious jumpers and must have a completely secure lid. Their extraordinary beauty makes them worth the effort and expense for dedicated reef aquarists.
