Mine was sick (maybe?) when I got him. He's healing from a serious fin rot incident.
His ventral tips were white to begin with (part of the reason his name is Patriot Red-coat the 8th) but when his caudle fin grew back in it was clear. I think 1f2f and Adastra are right. This is probably
just fin growth. Whether he was previously sick or he is just growing older.
I think he's fine as long as it's not fuzzy or anything.
Just to make sure, though, keep his water very, very clean.
