Sapphire fish can be mixed with other fish.

Ruby fish, golden pineapple fish and sapphire fish belong to the cichlid family and can be mixed. But ruby is somewhat aggressive. Therefore, the size of other fish in polyculture should not be too small. The sapphire will be sucked into the mouth together with the bottom sand when eating, so do not put it in the grass tank for polyculture.

In addition, pineapple likes salt, and should be regularly Add a small amount of table salt to the water (20-30 grams of salt per 100 liters of water) so that the color of the fish will be more beautiful.
