Carassius auratus
Origin: Captive bred
The Premium Tosakin Calico combines the Tosakin's iconic, undivided butterfly caudal fin that fans out horizontally in a unique rounded spread with the spectacular visual depth of nacreous calico scaling in red, black, white, and blue. Sourced from specialist breeders, this variety is best appreciated from above in a shallow display setup that reveals the full three-dimensional spread of the extraordinary tail form. One of the most specialized fancy goldfish in existence.
Best housed in a large, shallow display tub or wide pond (60 cm depth maximum) to fully appreciate the horizontal tail spread from above. Very strong filtration essential — Tosakins are sensitive to poor water quality due to their extreme tail form affecting swimming efficiency. Feed sinking gel-based foods to prevent swim bladder issues. House only with other slow-finned fancy goldfish. Perform regular 25–30% weekly water changes.
