I cant tell from pick but my suggestion regardless... frequent small water changes to keep the water pristine, and feed at least 3 times a day to keep health/immune system good. more like 5-6 small feeds a day if can. and soak the food in zoe and zoecon to make it as nutritious as it can be.
afa the spots maybe lympho(whatever?) I forget how to spell it, sometimes confused with ich.
