For the past 4-5 weeks I have been feeding my albino checkereds fish and recently received some pinks from Layne Labs and fed it to them yesterday. They went crazy for it as if they were starving and there was a food fight and 2 of them had a tiny drop of blood on them, 1 had a drop near its nose and the other on its mid-section. I separated them and cleaned off the blood with some water. My question is.. Is it a necessity to use some sort of ointment or treatment on their tiny wounds?
