Pomacentra.

Note: there is only a yellowish stripe on the back; there is no coloration on the head, it's a glare. The fish is 10 cm in size, with a body shape similar to that of an Astronotus.

The family Pomacentridae includes up to 10 genera and numerous species, which can be difficult to determine accurately. (Some references even mention more than 30 genera and 300 species.)

If the body shape with fins resembles an astronotus (although this is not noticeable in your photo), it could be Centropyge nox. If we forget about the astronotus and think about pomacentrids, it could also be Stegastes nigricans. The photo is quite unfortunate.

Tomorrow I will post other photos, maybe something will become clearer there.

Most likely, this is Paraglyphidodon melas juv. (Black ...) in adult coloration.

Maybe this one?
