It was fine this morning and now a few hours later it's dead...
I only have an ammonia test kit but it shows up as 0. 50% weekly w/c, last changed on thursday and today's saturday so I don't think the fish was shocked from the w/c, and I dosed prime. Tank established for over a year, 3x recommended filtration and 13x turnover per hour. Only other thing I've added recently is seachem flourish, but the other angelfish in the tank are fine.
Pics: There is red on its head and fins. I have 2 or 3 more angels in the tank with slightly red fins like that, but not on their head. Is it signs of ammonia poisoning? I do not have ammonia in my tank, but I do feed heavily because I want to ensure that the corys get their food at the bottom of the tank. Am I causing the ammonia to spike after feeding?
Also, this angelfish has 2 lines(scratches?) on its body...did it get stuck on something? I took all rocks out...only sharp things may be small pieces of eggshell that I added for calcium or a piece of driftwood(highly doubt it). Do you guys think it may have swallowed some eggshell?
