My turn for some help

[Stingingrays]

okay my one male motoro has what looks like a gill flap missing and then there is another spot..........

Water parms..... pH7.0, amonia0, nitrates0(or nitrites can't remember)

He is great swims around and eats like a pig like normal but I just want to make sure if this is something to worry about or not.

These are the best pics that I can get, he doesn't like to go up the glass much.

it is nitrites 0. 180 gallon tank, 4 motoro's and 1 retic rays in it. 3, 50% water chagned a week.

They are fed live black worms and ghost shrimp.

The spots are normal. There kind of like a birth mark. Some of my motoros have one or two, some have many. Nothing to worry about.
