We got this lil guy (or gal) sold to us as a green chromis. But I’m not certain that’s what it is. Anyone know what it could be?

Not your typical blue-green chromis. Yours appears very similar in shape to staghorn damsels, thus I imagine its in the genus Amblyglyphidodon. Yours looks very similar to Amblyglyphidodon batunai. I do not think it is a chromis.

Here is a link to a photo of the species I mentioned earlier that looks very similar to it. My bet is a juvenile damsel related to this species, juvenile coloration and shape differs quite a bit from adults. It is likely that it was just mislabeled and misidentified because the people who sell and trade fish aren't exactly scientists. I'd like to make it clear that it is very unlikely to be a chromis, just a different type of damsel. Although it is likely to behave very similarly, it is likely a plankton feeder just like chromis (which is simply a genus of damsels).

Thanks for the info will check into it!

Agreed. Body shape is more of a damsel fish then the cromis. Not sure which damsel fish though..

we came across a Divers Den post today of a “golden damsel” (Ternate Damsel) and that caused a double take lol! I really started to question my “green (or blue green) chromis”

That is in the genus that I mentioned. Doesn't it look much more like this fish than a blue-green chromis? It is most definitely not a chromis, especially not a blue-green chromis. Those tend to have a more ovular shape. I can't help but keep repeating that what you have is NOT a chromis at all.

To put it simply, a genus is the lowest level of the basic classification of taxonomy that is not a species level (the specific type of animal). Animals that share the same genus are very closely related, genetically, and thus tend to look very alike. Chromis is a genus of damselfish, and they consist of mostly shoaling plankton eating fish that are ovular in shape. Amblyglyphidodon is another genus of damselfish, and they also tend to be shoaling plankton eaters, but they tend to be more stout and circular in appearance.

Most important thing to note is that if you put in an actual blue-green chromis, they are unlikely to stick together and shoal in any meaningful way (although in the wild you will see Chromis shoaling among coral with other damsel species Dascyllus so never say never), they might not even get along to be honest.

Yeah... we were thinking it’s not chromis... lol! my husband told me he didn’t think it was a chromis shortly after I added it to the tank.
I’m just hoping this lil one continues to be a nice tank mate..

Thanks so much for all the info!
