7 things to know before welcoming a Mizuiro Kikyou Medaka
1Blue lame and fin sheen
Mizuiro Kikyou builds on the long-finned hikari-type body of Aomiyuki, adding blue lame and a strong sheen on the fins. Its long fins and their sheen look their best viewed from the side in a glass tank.
2Fewer bent spines
Long-finned hikari-type medaka are often prone to spinal curvature, yet Mizuiro Kikyou is said to show less of it. That said, individuals vary, and it is not a guarantee. When choosing, check the body line in photos or videos.
3Good for beginners
Its care difficulty is rated beginner-friendly, so it is a good fit once you have the basics of keeping medaka down. Use dechlorinated water and avoid sudden changes in temperature or water quality. Feed only what is eaten in a short time, since overfeeding fouls the water.
4Size and container
Adults are small, so you can start with a fairly small container. Because the fins are long, a container with room to swim shows off the fish better. Avoid overcrowding and keep a comfortable number of fish.
5Keep the flow gentle
Long-finned fish tend to swim more leisurely, so a strong current can be tiring for them. If you use a filter, soften the flow by adjusting the outlet or choosing a sponge filter. Plants and hiding spots help them settle in.
6Choosing tank mates
Medaka are generally peaceful, but a long-finned individual may get chased by fast swimmers or lose out at feeding time. If you keep them with other fish, it is safest to stick with other medaka or calm, small companions. Compatibility varies with the setup and the individuals, so watch closely at first.
7Getting ready
Set up the container, dechlorinated water, and any filter or plants beforehand so you can welcome the fish calmly on arrival. Float the bag on the surface to match the temperature, then mix in a little tank water at a time to acclimate them. Go light on food right after arrival and watch how they settle.
