This little guy may seem very plain at first glance, as they are often seen very paled out when at the LFS. Upon introduction to your aquarium, they will start to assimilate the colors around them, while keeping a nice stark white base.
Their real color is behind their pectoral fins and is the reason behind their common name, “Flasher Scorpionfish”. Watch the videos included, to see some quick flasher action.
They are often confused with Scorpaenopsis diabolus, which is a much much larger fish. Be careful you know what you are buying because the macrochir can go in a nano-pred tank, while the diabolus can be mates with a volitans!
