Help with Emperor angelfish

[herpinsaquarium]

Hi
Today I noticed a line on my emperor. Is it something I should be worried about?

Why is that?

I also gave a list. It needs certain meats, sponge, vegetation and fatty acids and what you’re giving it lacks some of that criteria. Part of it is not bad foods but a vitamin deficiency. Water quality just as important.
Mag is quite high. (1300 recommended) and calcium low (440 recommended) and ammonia a bit high (<.025 recommended )

My ammonia is 0, it's nitrite 4. What do you recommend on terms of vitamins? I already use AF garlic oil and fish V. I have not tested calcium in quite some time, as I use a calcium reactor and my understanding is that it doses calcium and ALK in a good raitio. For the mag, I would need to test it again, as I run it in the calcium reacto as well

Selcon vitamins are fantastic 3-4x per week and garlic extract on alternating days
