Tosanoides flavofasciatus has never been available outside of Asia (and even in Asia, it is extremely rare). Unless you live in Japan, I very much doubt hobbyist will see one come their way any time soon. For now, we can enjoy these photos.
I'm a passionate aquarist of over 30 years, a coral reef lover, and the blog editor for Advanced Aquarist. While aquarium gadgets interest me, it's really livestock (especially fish), artistry of aquariums, and "method behind the madness" processes that captivate my attention.
