Hi All, I recently started an aquarium and got two gouramis and one molly. One of the gourami has black minute spots all over its body. It may be natural to have this but just want to confirm if that is not due to any disease. I first had two gouramis and two molly but lost one due to bad water 3 weeks ago. ammonia - 0.25 ppm, nitrite - 0.25 ppm, nitrate - 40 ppm. just did a water change this morning but did not take readings after that. Fish is doing ok though. I am unable to add a pic which I am trying to sort it out now. I want to confirm if there is anything wrong with the fish or water? Thanks.
