i agree that the fish looks a little different, but would still lean toward Florida gar since it came from an LFS and we are still in early season for those fishes, and probably a bit too early for wild spots (wherever they may be collecting them). that and since they are in Cali, i would imagine they are coming in from "farm" collections.
just say a tiny FL gar at the LFS (fish drs) today...same size, pattern somewhat variable.--
