I recently noticed some "5 o'clock shadow" on my male Betta. I am wondering if this is velvet or some other fungal infection. He is not showing any usual behavior (any of the symptoms of velvet besides some discoloration), the females that are in the same tank are not showing the same thing, and he has been eating. I don't remember this being here, but I have not had him that long.
I am going to the pet store on Saturday and want to know if I can pick something up for him. I am having an ammonia issue with their 10 gal tank that I am working on fixing. Is this something that I should be concerned with? He is such a cutie and I don't want to lose him :(
