I'm not sure this is a real issue, but spots have been developing on my betta's ("Betta") pectoral fins. It is very similar to this post:
Gravel bottom, live plants and ornaments.
Heated, 80 degrees
Rotation of Bio-Gold pellets, some generic betta pellets, freeze-dried bloodworms, freeze-dried shrimp, and frozen peas
Once a day, 3-4 pellets
Bi-weekly water change of around 50%.
Only additive is water conditioner with the occasional melafix for fin tears
Tested several months ago
Symptoms and Treatment
See picture below. He has almost always had a black spot on his right pectoral fin, but now he's got a couple. Is this anything to be concerned with?
Thanks in advance for any advice!
