is there any way to determine the difference between the 3??? I just bought one about 4" from a LPS and these guys have great fish but are morons when it comes to labeling. I have seen GT labeled as JD and butti labeled as Frontosa. These guys told me it was a Texas Blue but I only paid 19.99 so I thought it was worth it what ever it was... it's a gorgeous fish. Any markings or anything that can be used to tell???
