Try adding some iron to the tank. When Ap. nijsseni first was imported,
the iron adding to produce the red in the ring was widely discussed.
I've always added some iron to my tanks (for the plants mainly) and
the Ap. nijsseni seem to benefit nicely. Mine (captive bred in Denmark)
have very nice red rings.

Diet should also be important. Lots of shrimp/beta-karotene should provoke
some red colour (just look at what's in the Tetra Rubin and similar products).
