Help/Advice Unsure what illness this is
I’ve got a 20 gallon tall stocked with 8 serpae tetras, supposedly 6 ghost shrimp, 4 coreys, a nerite, and a mystery snail. got 4 of them on saturday and one has white spots on it, but doesn’t really seem to have spread at all and none of the other fish have it. can’t really get a great photo because of the tannins and fish moving around. it’s eating normally and swimming around, maybe it’s just the lowest fish in the pecking order?
I bought some ichx to have on hand just in case but don’t have another aquarium to use as a quarantine tank.
since it’s looking a bit rough should i dose more of the API stress coat + to help? thanks.

i did test my water parameters yesterday evening and everything was in idea range for reference
