Sure, the small ones will be quite jumpy and avoid the monsters the first couple of days, but they'll mix comfortably within a week. The 2 15cm tosai (SFF kohaku) is no less than 45cm now in a matter of 7 months, and should easily reach 60cm by October. A 18cm Izumiya Yamabuki bought last December is also about the same size. However, I would reccomend introducing a pair of yearlings if you plan to mix them with the adults... they'll need less time getting used to the new environment if they have company. The faster they adapt, the more comfortable they are to feeding. -Dennis

Thanks Dennis for the information. You seem to have quite a good collection of kois in your pond and they grow very fast!
