The Marbled Tainaiko is a fancy breed of Japanese Rice Fish. This is quite an odd medaka. The name literally means internal (Tainai) light (ko) marble. I believe there are different versions of Tainaiko, but this is the marbled variant. It is quite hard to describe this fish; it has a gray to black coloration with a metallic sheen making it seem like it is glowing from the inside. I don't believe it is actually bioluminescent in anyway.

You will receive 6 medaka as well as 1 or 2 additional bonus medaka per group. We can mix and match different breeds of medaka of equivalent value or less on request. Please check our list of breeds to see what we may have currently not listed. We may not always have enough for an order, but we may have 1 or 2 of a particular breed available.

  • Availability of rice fish will depend on the availability of a vacant pond during spawning season.
  • Please be aware that there are no guarantees on all livestock once the bag is opened. Please contact us and send images/videos immediately if you receive livestock that is dead on arrival.
  • Goldorado Aquatics currently only ships to the 48 states in the contiguous United States.
