I concur. As others have said, there are actually several cichlids that are sold as "chocolate cichlids", but that fish appears to be
Hypselecara temporalis. The problem is a lot of people muddle up that species with
Hypselecara coryphaenoides, and you'll also see the name
Cichlasoma hellabrunni used a lot, too, for either species. It was once thought these were all the same fish, but now
Hypselecara coryphaenoides is apparently treated separately, as the Rio Negro chocolate cichlid.

Years ago, I kept these fish. Not especially aggressive in a big tank, and certainly you can mix them with catfish, silver dollars, and things like pike cichlids that keep themselves to themselves. They have an astounding ability to change colour, from red to yellow to green. No two specimens look the same.
Feed primarily on worms and insect larvae, but will eat small fish (neon tetras!) if no other options are available. There's a picture of your fish (though labelled as
Hypselecara coryphaenoides), in Loiselle's "The Cichlid Aquarium", page 91.

i am confident it is a a Hypselecara temporalis aka Chocolate Cichlid
