How to tell the difference is not by coloration, also not by patterns. I have seen wild caught with almost have ] royal stripes patterns but never seen one with alsmost no patern or have spotted pattern which is common in captive breed. There is also the max possible size and head shape. Most captive breed delhezi have slights popping eyes and also if you look at the snout starting from the eyes to the tip of it's lip, it a bit shorter compare to wild caught. Wild caught can grow bigger also they have pointer snout but this does not always apply. It's hard to tell in juveniles btw.
It's best to get bichirs from a reputable dealer if you want to know if it's a wild caught or not. That's the only way to tell 100%. Guessing from LFS and even if the dealer say it's a wild caught, it's not 100%.
