fish are definitely back up to speed. swimming all over the place. so the treatment worked for whatever this issue is. i still have no idea. i looked around but could not find much.

I have a good photo for any records of this otherwise weird complaint. I have noticed this whitish / silvery discolouration on one of my my 90mm clowns. Have been looking for answers until is spotted this article. I shall upstage the water changes, formally was changing 25% every 10-14 days...
