I got a Golden Black Moor about a month and a half ago. Today I noticed on his tail fin is a small red splotch with a smaller black splotch below it. Also he is becoming more aggressive to the other fish in the tank. Anybody know how to fix the little guy?

how old is he do u know

What are the nitrate, nitrite, and ammonia readings (looking for ppm)?
Anything sharp he may have nicked himself on?
Has he been netted recently?
What other fish do you have in the tank? (Your aquarium info just lists the moor)
First guess with a red spot would be ammonia poisoning, but there are other possibilities.

What other fish are in the tank with him?
Have you checked your water parameters?


Edit: SDS types (or thinks & reads) faster than I do.
