Ever since i got my one spot fox face its yellow color is very pale compared to most of the ones I've seen that are deep yellow. it seems to be healthy and active but i want to try to get that deep rich yellow everyone else has. so far he has been eating nori, live algae and i feed mysis and spiraling infused brine. I'm stumped. all my parameters are perfect as well. Alk 8.5, cal 400, mag 1380 ,ph 8.1, phosphate .03 ,nitrate .50 and potassium 400.
