[Perchance]

Gah, I'm not sure if I have a weird fungus or bacteria in my tank. One of the Rsboras had a white dot on it's lip. Could it just be white spot in an odd place, or should I look into mouth fungus type infections?

I don't know what to do. I have a tank I can set up for quarantine, but I can't for the life of me even catch them.

Should I start medicating the tank? The water being at 30C for the last 4 days hasn't done anything, I don't think. New spots appeared today.

Edit: I emailed Aquasonic (Australian brand for most aquatic supplies which I can actually get locally) to ask if their products are plant safe. And I photographed the fish with the white bump on his lip. I will upload these and some extra photos tonight
