Aquarium Advice Apprentice
My baby goldfish has developed a bright red face over about 2-3 days, it seems fine otherwise. Does anyone know what it is. I don't even know what type of goldfish it is because there were eggs in aquarium plants I bought for my tropical tank. It's 10 weeks old. I bought a Calico goldfish 1 week ago from a pet shop for a tank mate but it suddenly died overnight. The water tests are fine. Can anyone tell me what's causing it? If it's a disease can it be treated & how? & what type of goldfish is it?
