Hey all, Back when I had my cuttlefish, I brought one of my babies to the LFS I work at. The water in the system which the cuttlefish was going was perfect, except for nitrate levels at about 20ppm (which is high for ceps). As a gamble, I went ahead and slowly drip-acclimated the young cuttle into the the tank water. The entire process took about 2 and a half hours, as I wanted to make sure the drastic change from 0 nitrates to 20 nitrates was slow. After the acclimation, the cuttle was released into the system and monitored throughout the day. Colors were darker; the cuttle maintained a dark black skin color for at least two hours. After a while, I witnessed a strange change in color of the eye. Blue and pink colors were seen. Any thoughts as to why this change occurred? Could this be related to nitrate poisoning?
