Aquarium Advice Regular
I recently increased the temp in my tank to treat ich in 2 of my fish (a platy & black skirt tetra) - this morning I see one of my danios swimming listlessly (tho not gulping for air) at the top of the tank with a red belly. My ammonia & nitrite levels are fine - nitrates seemed a little high after I did a large water change - 10-20ppm - hard to tell with the color chart. Could the fish be constipated or nearing its demise?
