It is normal for a pregnant guppie to have a reddish interior on her Travis spot
There will be a dark spot in front of the fishes anus (cloaca) in a pregnant (gravid) female livebearer. This spot is called the "Gravid Spot".
If light rays are focused directly on the blind spot in the eye, those particular light rays would not be detected by the retina because the blind spot is the area on the retina where the optic nerve exits and there are no light-sensitive cells present. This would result in a gap in the visual field where those light rays are not perceived.
With a guppy you need to look at the gravid spot. This is a dark spot in the fish's belly. A large gravid spot indicates the fish is likely to be pregnant. You can tell how pregnant the fish is by how large the spot is. Sorry I have no experience with other species.
