Cichlasoma ID

[NHKG]

Bought as Krobia itany, German bred.
I think they could be Cichlasoma portalegrense or Cichlasoma amazonarum.
Any idea how to distinguish these 2 species? Or it could be some other specie?

The middle picture looks like it has only 3 hard anal fin spines, which would leave out amazonarum. There are several 3 spine species, of which portalegrense is one if I remember right. But I'm not good enough with the group to nail down which specific one it might be.

You might ask a mod to move it to the CA/SA folder, there are few peeps there that keep port cichlids and might be able to give you an ID.

Nope, 4 hard anal fin spines. Counted on biggest male.

I found this thread: https://www.monsterfishkeepers.com/forums/threads/identifying-your-cichlasoma.366569/

4 hard anal spines + the heavy scalation of the anal and dorsal fins, with several rows of scales entering both fins => Cichlasoma amazonarum.

Yeah, the bottom picture of the two new ones you added it does look more like four, but I wasn't sure enough to post. Counting of course would be more definitive. With the four rays and your last pic, amazonarum seems a solid pick.
