The seven-color angelfish and the parrot fish cannot be mixed, because they are different in terms of diet, personality, and environmental requirements:
1. From the perspective of diet, parrot fish has a demand for color enhancement, so it is mainly fed with artificially synthesized pellet feed; The seven-color angelfish mainly eats live bait, such as small fish, shrimp and so on. Bacteria on small live fish can easily contaminate the gills of parrot fish.
2. In terms of character, the character of the seven-color angelfish is relatively timid, and it is easy to have the problem of not eating after being frightened; But the parrot fish is active and lively, and likes to bite other fish, so the two personalities are not suitable.
3. In terms of environment, the water quality of the seven-color angelfish is relatively high and needs to be absolutely clean; Parrot fish can pollute the environment in terms of diet or physiology.
So from the above, the two are not suitable for polyculture.
Seven-color angelfish and arowana best not mixed culture together. Because the dragon fish character is more irritable, has the very intense territory consciousness, and the size is very big, the body length usually surpasses 40 centimeters. They can easily attack angelfish that are only a dozen centimeters long. Moreover, arowana has more stringent requirements for water quality, and the water quality that the two kinds of fish like is not the same. This subtle difference can also cause discomfort in fish. Therefore, it is better not to mix them together.
