White Cloud Mountain Minnows Breeding

Breeding White Cloud Mountain Minnows can be a rewarding and relatively easy process. Here is a step-by-step guide on how to breed them:

First, set up a separate breeding tank with clean water and suitable conditions. Use fine-leaved plants like Java Moss or spawning mops as hiding spots for the eggs.

Next, choose healthy males and females for breeding. Preferably, choose one male for every three females. Feed them a nutritious diet to prepare them for breeding. This helps improve their chances of successful spawning.

Now, introduce the pair to the breeding tank and provide plenty of hiding places. The male will chase the female, and she will scatter the eggs among the plants. The male quickly fertilizes the eggs.

After spawning, remove the adult fish from the breeding tank to prevent them from eating the eggs. Put them back in their original tank.

The eggs will hatch in about 36-48 hours. Maintain stable conditions and clean water during this time. The fry will initially feed on their yolk sacs before transitioning to small live foods or powdered fry food.

As the fry grow, gradually introduce larger food options like baby brine shrimp or crushed flake food. Keep an eye on water quality and perform regular water changes. Provide hiding spots for the fry to keep them safe.
