In fact, it stands to reason that all ornamental fish are actually quite sensitive to red things. The so-called sensitivity means that in the eyes of most ornamental fish, red represents danger or toxicity, which is an unwritten rule in nature.
3. Once, a foreign scientist did an experiment by himself, keeping the same goldfish with red, white, blue and black background paper. The results showed that goldfish with red background was the most depressed.
In fact, this phenomenon is not surprising at all. At that time, the authoritative books on raising ornamental fish once wrote that goldfish can easily get white spot disease if they are exposed to red light for a long time. Maybe this question is not as exaggerated and absolute as the book says, but there must be some truth.
5. If you don't believe me, there are friends who keep ornamental fish such as arowana, tiger fish or colorful fish at home. We can suddenly change into red clothes and dance a swan dance in front of the fish tank, and then we will see the chaotic reaction of these ornamental fish in the fish tank, so we must be careful with the red background paper.
