Reason: traffic light fish often die may be the temperature difference is too large, they are tropical fish, like a little higher water temperature. Artificial breeding, can not guarantee that the water temperature has been constant.

2,. High density. Reason: the traffic light fish often die may also be because of the feeding density is too high, although their size is not large, the requirements of the activity space is not high. However, too much density may cause death.

3, poor water quality. Reason: the traffic light fish often die may also be too poor water quality, they are on the high side of the water quality requirements. If the water quality is weakly alkaline or neutral, it will lead to a lot of discomfort for them.
