       大部分發生在大陸進口包金（黑、紫、黑紅、黑黃）及熊貓（黑白）金魚身上，養一陣子或用活性炭過濾後，魚體上黑色素開始褪色，褪掉的體色有可能還會局部還原，但已失去觀賞價值，應屬基因不穩定所致，對金魚的健康無害；另有一說，高濃度鹽浴會使魚體色淡化，故鹽浴時間應遵照規定，鹽浴後應即換水稀釋。

Most of the imported goldfishes from China are easy to cause the fading problem, such as; wrap gold in black or violet or black-red or black-yellow color or panda (black-white). After keeping a period or using the charcoal in filtering, the black color of goldfish would be starting to fade out; a part of fading body color would be recovering in sometime, but it’s losing the enjoyable value.

The color fading might be caused by the unstable gene, but it’s not affected to the health of goldfish. In other word, the higher consistency of salt dosage would also be affected to color fading, thus, the timing f salt dosage should be complied with the affiliated regulation. And, the water dilution is recommended with changing water after the salt dosage.
