I have a really dumb question regarding rays: About 2 weeks ago I noticed my male mantilla develop these greyish spots on the underside of his disc. Didn't think much of it until I noticed they're appearance changed every so often. Occasionally, I'll notice that he twitches his disc a little. Also, he doesn't seem as eager during feeding time. Could all this be linked? My w/c routine hasn't changed (approx 20% weekly) pH 6.2, ammonia 0, nitrate 0, nitrite, 30 (i think) and his tankmates (motoro and jardini) seem perfectly fine.

Oh, and sometimes he stirs up the bottom by moving quickly across the bottom in really tight circles. Here in aus, we would probably refer to it as "ripping donuts".
Can you get pics of these spots. And video of him "ripping Donuts "

Tried to get pics of those spots but he's just sulking on the bottom now not moving much. Now that he's sitting still, I've noticed hes got a cloudy eye. He's hardly ever exposed to direct sunlight so would I be right to assume its a bacterial thing? His tankmates are still behaving normally
