After laying eggs, they should be fished out immediately, so as not to eat the eggs. Or use a plastic sheet to form a funnel-shaped partition wall, intrude into the water, and place the larvae in the funnel, so that after the larvae are born, they fall from the hole under the funnel into the water outside the funnel, and the female fish cannot eat the larvae.

The necessary measures should be taken after the one-line corrugated hanging egg is laid. For anti-inflammatory and disinfection measures, methylene blue, potassium permanganate or salt can be used for disinfection to prevent the deterioration of wound infection.
