swallow fish is not difficult to raise, and many initial breeders can raise it well. There are many kinds of swallowfish, but I think marble immortals, zebra immortals and tiger skin immortals can be used to practice their hands. Swallow fish is suitable for weak acidic to neutral soft water with pH value of about 6~7, but now most of them are artificially improved varieties, and they can also adapt to weak alkaline water with high hardness. Generally, the average feeding water temperature is only 26~28℃. In addition, swallowtail is an omnivorous fish, but usually it is also possible to feed some silkworms, Daphnia and artificial feed in aquarium stores. And don't mix with large carnivorous fish when raising, otherwise tragedy will happen, and pay special attention to the fact that tiger skin fish has a hobby of biting the ventral fin of swallowtail fish, so don't mix with tiger skin fish.
