The reason that the herringbone does not eat may be because the water temperature has changed too much in a short period of time, and the herringbone will be very uncomfortable with the water temperature and cause a refusal to eat. It is also possible that the nitrous acid content or the nitrogen content increased sharply. For example, the animal bait died at the bottom of the tank, and the nitrogen content in the tank increased sharply after it was not cleaned up, or the ammonium nitrite increased sharply due to the decay of the plants at the bottom of the tank. This is due to the chemical reaction of various residual substances in the tank, which leads to a sudden change in the water quality, thus affecting the appetite of the herringbone butterfly.

When these situations are encountered, if you can move the fish, move it immediately If the herringbone butterfly is placed in another tank, if it is not moved, it is only necessary to add water immediately, the sooner the better. Do not use tap water that has not been dechlorinated when mixing with water. It is best to reserve some dechlorinated water in case of emergency. The bad water in the original tank should be completely replaced, and the tank should be cleaned and thoroughly cleaned.

Prevention is more important, otherwise it may cause the death of the whole tank if you are not careful. Therefore, the above situation of deterioration of water quality should be avoided.
