The best temperature of Pacific Tengu hanging water is 25℃～26℃, weak alkaline water, pH value 8.1～8.3, salinity 1.021～1.024, oxygen demand (6～7)×10-6. To clarify the water quality, in addition to adjusting the water quality by adjusting the aquarium equipment, controlling the amount of bait for marine fish, and feeding the bait on the principle of small quantities and frequent meals, is also an effective means to maintain the stability of the water quality.

Water temperature has a great influence on the feeding intensity of Pacific Tengu hanging . In the suitable temperature range, the increase of water temperature has a significant effect on the feeding intensity of Pacific tengu. When the water temperature decreases, the metabolic level of the Pacific tengu fish also decreases, resulting in loss of appetite and stunted growth. Pacific Tengu can only be healthy and less sick in a good environment.
