My experience is limited, but I have found the smaller species (T. Butlerii and brachiostoma) to have a faster metabolism than the bigger types, and to be somewhat more vulnerable to low humidity and shed problems.

You should find the bigger species a breeze. Same care as the little guys, but they are even tougher and more resilient to less than ideal conditions- I think this is why the larger species have wider distribution
The little guys can out reproduce/compete them when conditions are just right, but outside these moist microsystems the bigger species toughness becomes an advantage.
