So I come home tonight look in one of my tanks and see that something's growing on the side of my hoplo. It doesn't look like ick to me and it flutters as he swims through the water attached to him. I've never seen this, I've had him for right around a year now with no issues just want to see what this is, see if it's contagious, how I should treat it? Any help would be great. Attracting pictures below.
