sorry to be vague but mainly checking tjat it won’t harm them by adding treatment? also to check if it could be something else and to ask if it is ich whst treatment u recommend that won’t affect fish or snails and conch. here is a photo but he isn’t very easy to take pics of, there doesnt seem to be many dots but they have been there for at least 1-2 days now so i can’t see it be sand, he is 6 years old and i have another clownfish and a royal gramma that seem fine, í noticed a few days ago he had been not very active and he lost his appetite for a day so i tested all perimeters and my nitrite were pretty high so i did a water change and it’s going down but all my other fish seem fine so assuming it might not be related? he seems better today he’s swimming around with his partner and eating pretty much like normal (which is a lot) and was yesterday aswell? any help ís appreciated í hope ím just stressing over nothing
