They wont have much differences, you got to have a few different catch location before seeing the differences between them, substrate can change base color.
From what i have i noticed that faranah endli have more flat head and rounder snout than dabola endli, dabola endlis head is more bulky and square snout, black volta endlis have more
Pontier snout and head shape seems to be longer.
For the base color i have faranah endlies looks more grey, dabola endli have more brownish/tan and black volta is more darker tan, they on the same substrate so that just imo.
Just remember a platinum senegal is cb also so no garantee that they will grow 10"-12", even if thwy do they might take years, ive just noticed that you have a 10" ornate and a growing koliba, ornate can be aggressive, maybe not now but you never know when light are off. Just a warning if you really going to get a plat sen.
