I caught this fish in a canal in South Florida that I believe is brackish because I also caught some Florida Gar. At first I thought it was a Blue Gill but I am wondering if it might be a Mayan Cichlid. It looks too elongated and small to be a Blue Gill and I don't see a black spot but I am not sure.
It is about 5 inches long. Could someone identify this fish? I have caught 9-10 of them that were this size and then I caught a fish that looked a lot like it but was a few sizes larger (like 300% bigger in length and width) which I am not sure is a bigger version or a different species.
