How to Choose Discus Fish? These Buying Tips You Need to Master
How to choose discus fish?
The main points for choosing discus fish are:
First, the eyes of juvenile fish do not have to be red, but the smaller the eyes, the better. Be careful not to choose ones with white-clouded eye membranes or eyes that are asymmetric left and right.
Second, the fins must be able to extend freely and show no signs of damage, the dorsal fin must be tall, and the scales must be smooth with no reversed scales.
Third, the vertical stripes on the sides of the body must be symmetrical left and right and even in thickness.
Fourth, the rounder the body shape, the better.
Fifth, the fish body should have no white spots or overall blackening or other warning signs of disease, the gill covers should not be turned outward excessively, and the fish should not show abnormal behavior such as rubbing against objects in the aquarium.
Sixth, in the same fish tank, choose the healthier fish. You can stir the water surface with your hand; more than 95% of the fish that come first to grab food are healthy.
Seventh, after choosing the discus fish, you should ask how they are usually kept, such as the pH value of the water, water temperature, and so on.
Eighth, before putting the fish into the tank at home, be sure to first let the fish body adapt to the water temperature, so as to help the fish adapt to the new environment.
