Calappidae
Harlequin Shrimp
Hello, My sailfin tang turns yellow after being fed, the pupil in its eyes also stick out more in color. (their pupil is pure black while the line going down is more of a yellowish grey) and whenever it swims around.. I looked at photos and videos of them and I never see them do that.. is this a disease of some sort or is this a normal behavior? I have a decent ammount of hair algae and all the tang does is pick at it.. I even noticed a decrease in dark green slime aglae. When ever I turn the light off it acks normal.
