I am having an outbreak but I'm not sure if it's fungal or bacterial. It started as small white spots on my angel fish but only fins not on the bodies. Now it seems to have spread to my neon tetras. It is on a couple of them. Find deteriorated, white, one has a sore on its body and another has something on its mouth. All fish are acting normal. And it has not spread to all my other fish (yet). The tank is a couple years running. I am not sure of water parameters as Ido not have a test kit. 75 gallon community tank with weekly 30 % water changes, never missed. Please help.
Thanks for your time.
