No, that's just their normal eye color.
Simply a marking on the fish. Do not worry about normal marks.
A red, bulging eye with no visible pupil in a guinea pig could indicate a serious condition such as a corneal ulcer, glaucoma, or an eye infection. It is important to seek immediate veterinary attention as these conditions can cause pain and potentially lead to vision loss if left untreated. Observing one normal eye does not rule out the severity of the issue in the affected eye.
It could just be blood so here eye's are blood shot and that's totally normal. If your really worried about this ask your doctor.
It's not normal, but it's probably not harmful either. It's like a human having one blue eye and one hazel eye. I suggest seeing a vet about anyway.
No, because the eye is getting infected. It can be because the shih tzu has red fur on its face. Have you ever seen your shih tzu paw is face? If so, yep, the eye is getting infected. You should cut the red fur from the face carefully, or take your shih tzu to its professional groomer. After all the red fur is cut out of the face, your shih tzu will be fine... Just take him or her to their veterinarian to get some tips if your shih tzu's eye(s) is (are) okay.
Red is a color that is visible to the human eye, so it cannot be both red and invisible at the same time.
It removes the red eye infection to our eye. It removes the red eye infection to our eye.

Physicians use "gross" or "grossly" as descriptors meaning "absolutely", "positively", "majorly" "big time" plus whatever word follows. So "grossly normal" means "the macula is absolutely, positively, majorly, big time" NORMAL. The macula is part of the back of the retina, where the occular nerve enters. The macula and retina are part of the eye. Redness of the scleras (the whites of the eye) occur usually from irritation but not from anything abnormal with eye structures.
It's when you take out the red eye in a picture
No, they don't have red eye.
