Koi can grow to 1-1.5 meters. If raised in a small fish tank, it can only grow to two or three inches due to limited activity space; if you want it to grow large, you should put it in a large fish tank or outdoor pond, they will soon grow to 30 cm or more.

How do koi fish distinguish between male and female?

1, look at the body shape: abdominal hypertrophy is female; slender body shape is male.

2, look at the anus: anus wide flat for female; anus small and concave for male.

3. Looking at chasing stars: When males are about to expel sperm, reproductive nodules will grow on their heads and pectoral fins, that is, chasing stars. During the breeding season, those who do not follow the stars are female; those who follow the stars are male. Mature male fish will have white semen flow out when gently pressing the abdomen.

4, touch fin: there are rough horny protrusions for male fish; smooth for female fish.
