Hi Alexander,
I think that is pretty neat that you want to do a Taiwanee Reef tank. Listed below are all the species found at Taiwanee Reef. Of course a few of these are too big to keep with Chindongo saulosi. This is the new scientific name for saulosi.

Tropheops sp. 'taiwan' , endemic (Konings, 2006)
Tyrannochromis nigriventer Eccles, 1989, native (Konings, 2006)
I would say the fryeri from Taiwanee Reef is more orange than red. But a lot of this is based on diet. Often there is no difference between species from different sites.
If you access to any of Ad Konings books you can see what the species look like from this location. Also the Cichlid Room Companion has localties documented by photo's of a lot of these. Of course Protomelas sp. 'steveni taiwan' is one of the more popular ones that we see in the hobby.
