threadfin rainbowfish rearing
Whether indoors or outdoors, Swallow Beauty has a proven track record of breeding success. According to the experience of aquarium enthusiasts at home and abroad, there are several tips for the reproduction of Swallow Beauty. The most important of these is to provide dense mousse balls to seedlings as a medium for spawning. The larvae hatch in about a few days, and the newly hatched larvae are so small that they need to be fed with green water and small-sized microorganisms, which is the main reason for the failure of the swallow mermaid larvae breeding. Friends who are interested in breeding must pay special attention.
