MIPLUS Korotama Ball BIG Float Type - Set of 10

Features:
This is a spawning substrate for medaka (Japanese killifish) used in professional fish farms.
It's a next-generation spawning substrate born from professional fish farms, offering unparalleled effectiveness.
Made with materials and a shape that medaka prefer, encouraging them to lay their eggs.
The soft material is gentle on the medaka, minimizing injury.
The mesh structure of the material makes it easy for eggs to attach and less likely to fall off.
The material is water-resistant, allowing it to be washed and reused if it becomes dirty.
Replace when it no longer spreads out easily.
The number of eggs collected will vary depending on the environment, breed, number of fish, and individual fish condition. *Based on our laboratory research.

We also use MIPLUS Korotama Balls at our store. While some medaka YouTube channels show eggs being collected by hand, with Korotama Balls, so many eggs are laid deep within them that it would take too long to collect them all by hand. Therefore, at our store, we simply move the Korotama Balls to a separate container to hatch the fry.
