From my reading and through looking at other forums, I've found the following info:
1. The true grows slower and is a bit smaller @ adult size. (good for a nano)
2. True may require better water quality (plan to keep water @ reef standards)
3. True's may be a tad more aggressive than falses (anecdotally, people do not discern this. This is less of a problem with tank raised specimens)
4. False's tend to live in the middle third of the tank. True's stay near the surface.
5 And the characteristic that trumps them all....True's look way cooler!
Hence, my new tank mate...(a True Percula)
