I kno pics arent great but hes friggin fast lol. Whitish raised area on one side of my foxface. Have had him for maybe 2 weeks in QT. QT is a 20gal with a hob filter rated for 50gal and a sponge power filter. In hob filter there are 2 sponge filters and "bio media". Parameters are all good. Foxface is active as heck albeit a bit shy. He eats like a hog and attacks nori like a lion. Theres maybe some abrasions on side around bump but hard to get a good look as hes just to fast. Hes to favorite spots are wither in a clay pot or up between glass and pot. Hes currently in copper prophylacticly. Should i be concerned? Last pic is definitely best. I have NOT done fresh water dip yet.
