Can someone tell me what this is? I have attached an image of the Phantom Tetra I just lost. This is the 3rd fish is approximately 4 months, the other two were Dwarf Gourami. All three had the same symptoms, open sore on the right side...though one of the Gourami showed some swelling and redness on the nose. After noticing the sores, it was within a week the fish would stop eating and die. Thank you for all your input.
