25 Bobu Medaka Ricefish Eggs (Fertilised)

25 Fertilised Bobu Medaka Ricefish Eggs

You will receive 25 fertilized Medaka (ricefish) eggs from the fish shown in the photos. As hatch rates can vary, I will include a few extra eggs at no additional cost to improve your chances of success.

Please note that not every fry will develop the exact same colours, patterns, or quality as the parent fish pictured. However, once mature, Medaka are prolific breeders and can produce eggs on a regular basis, making them a rewarding fish to keep and breed.

These beautiful Japanese ricefish are known for being hardy, easy to care for, and suitable for both beginners and experienced hobbyists. A small amount of starter food for newly hatched fry will also be included with your order.

You can follow my breeding projects and see updates on my fish through social media:
