Does anyone know what this white spot could be on my boys fin? I feel like it appeared just recently, I've had him about a year.
For context: he's in a 10 gallon with live plants. Parameters are 0ppm ammonia, 0ppm nitrites, 0ppm nitrates, 7.5ph (a little Hugh which is why I have the almond leaf in his tank)
Thank you in advance
