Just noticed my endi being totally covered in small white spots this morning and I'm not sure if it's ick. It's the only fish in the tank being covered in these small spots. I hope someone could help me identify what are these small spots are.
Yep, that looks like ich to me. I think you caught it just in time.
Just use aquarium salt/kosher salt, raise the temp up to 84-86 for 2 weeks, and it should be gone. If it is on him it will affect the other fish. Treat the whole tank.
