Hi All,

This morning I noticed three black dots that appeared on my motoro. At first I thought it was just a piece of dirt or something that fell on him, but when I tried to brush them off they didn't move.

Other that, it also appears the outside of the ray was initially a little whiter than normal, however, after feeding this pretty much went away.

Any idea what may cause the dots? He's in an empty tank,with 4 gourami's, a raphael catfish and pleco (pleco's never bothered him).

For reference it's a 150g tank with 1 Motoro and 6 other small fish. Which gets a 50% water change every week, Water parameters look completely normal.

Do they move at all, perhaps fish lice. However, if you tried to brush them off, that would probably out rule that idea.
 
I know that nerve damage in fish often shows up as black dots, I do not expect this is what they are but thought it might be useful info

I imagine they are just markings?
