Any idea what that is? I was trying to find a pic of mouth cotton disease, but found none that'd look like that.
3 of my 10 rasboras have very tiny peck of white at the very tip of the lower jaw.
I know it's hard to tell, but just to show the size of it. It does appear kinda fuzzy, very small.
All fish are eating like they should, tank is cycled and 3 months old, ammonia is zero, nitrites zero, nitrates 10ppm, temp is 25°C, i have live plants and airstone at night.
One of them is excesively opening it's mouth and gaping
My quarantine tank is 2.5G, and i keep 3 otos in the main tank, so moving all the rasboras is no-go.
