For a while, my male molly fish has these white bumps on its head. I couldn't find any information about it online... If you type keywords "white" and "bumps" it always shows me "Ich". It doesn't seem to look like an Ich to me... Also as I understand if it would be an Ich, fish wouldn't be very active, it would try to scratch itself on the gravel, other decorations and etc. But this molly, even with these bumps is very active, swims around as quickly as other mollies and it DOES eat as usual. None of other fish seem to have anything similar.
I tried curing an aquarium with "Sera omnipur" medicine, which was recommended to me by fish shop employee. This medicine is "against the most common ornamental fish diseases". Tested my water with Pro JBL AQUATEST Easy 7in1 and everything seems to be normal.
So I want to ask you guys, maybe you can identify what's wrong with my fish?
