Not sure which species from the pic, but there are only 3 species. They are known as "chromides" and are the only Asian cichlids. That one is either a green chromide or a wild-color orange chromide.
definitely not a meeki. it has no red on it. i have not the slightest as to the ID of this fish though, maybe someone with more knowledge of fish will come along. good looking fish regardless
I have owned the orange variant of one of those for a year now. They can pretty much tolerate a very large range of salinities. I have kept mine anywhere between 0 ppt and 25 ppt! Depending on which tank I want it in
