Pics won't be of much help. The dots are so small that you could barely see them against the bright silvery bodies of the hatchets.
However, there is now a new problem I just noticed. There's several hatchet scales that have floated to the bottom. My best guess is they're coming from one that got injured the other day while I was doing a water change. Either it bashed itself against something or worse, I banged it with the siphon tube on accident while sucking up over the whole bottom of the aquarium. It had bloody bruises along the backside of the body and a badly tattered tail fin, but the bruises have since healed and it's moving and feeding perfectly normal. So idk if it's just damaged scales falling off or ANOTHER problem cropping up.
