BLACK SPOT

[pandapops001]

What is this, is it white spot for white fish, so that we can detect it

I've checked all the other fish especially my black molly, and i cant see any white spots on him, and i assumed that if white spot was in the tank they would all have it. Plus yesterday the silver molly in question was also a strange colour grey, but that seems to have gone altogether today.

I've been doing 50% water changes every other day just in case its something in the water, but the hood is usually down, and we have made it habit that we never spray anything in the lounge, specifically to protect the fish.

Please help, also my dalmation molly is acting very strange, she used to hand feed from me, and now i only have to look across, and she'll dart in the cave, and is rarely seen when lights are on,

I dont want to treat the water for white spot (ICH), if its not that, but i dont know what else to think - ammonia nitrate nitrite all great.

Regards

Where is this spot?
if its on the belly near the anal fin then its a gravid spot and is normal

if its anywhere else then it coulb be black spot disease
