How does the black map fish turn gray? How should it be solved

Insufficient light: Black map fish may turn gray due to insufficient light. Breeders need to ensure that they are adequately illuminated and expose them to natural light for at least 2-3 hours every day. Unsuitable water quality: It is also possible that breeders need to use light green water to breed them because of long-term white water culture. Illness: It may also be caused by illness, and breeders need symptomatic treatment according to their etiology.

1. Insufficient light

1. Reason: The gray of black map fish may be caused by insufficient light, and they have sufficient light when they are in their place of origin. If they can't get enough light when they are farmed, their body color will gradually fade.
