there is no difference between true red terror and red terror when asking to purchase them. the Majority of vendors or distributors refer to Mayans as red terrors. and then those are sold by LFS as red terros. now there is a difference between festae and red terrors there are plenty of pictures on this site and the web to compare them to each other. but if you want festae you will need to refer to them as festae when looking to buy and not red terrors good luck
