To follow an earlier post, I wanted to share a few more images of pomacentrids from the Red Sea. I’ve got two more species that I know, and one more that I’m not quite sure about, so I would welcome any input from folks more knowledgeable than I.My first species is Chromis dimidiata, the aptly named Half-and-Half Chromis. This fish appears to have been grabbed by the tail and dipped into a pot of paint. It’s one of the smaller of the clan at 8-9 cm, but can occur in very large shoals to make up for its diminutive size.
In this image you can see scores of Half-and-Halfs. Like many chromis, they shelter within the coral branches. Look closely and you can see some Scissortail Sergeants (Abudefduf sexfasciatus).
Next up is a rather fine fish, not overly colorful, but quite splendid nonetheless. This is Amblyglyphiododon indicus, the Pale Damselfish. This fish has a close relative A. leucogaster, which is found in the western Pacific.
My final fish is a real little beauty, the problem is I don’t know what it is. Clearly it is a juvenile and resembles many species from the Pomacentrus genus, but which one?
It quite strongly resembles P. nagasakiensis, but I really don’t think that’s what it is. If I had to put money on it, I’d go for P. trilineatus, though they always seem to have more yellow? If anyone can offer a definitive ID, I’d be pleased to hear from you.
