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.
