We keep our discus tank at 83 F.  It's a 100 g tank with 7 discus, a
few cardinals, 6 asst'd corys, 2 SAE and 1 farlowella.  It has 
CO2 injection (15 ppm), 100w DIY/Dupla substrate heating coils,
laterite, Dupla fertilizers, 4 40w FL bulbs @ 9 hours per day. 

The following plants are currently in the tank and doing well:

Anubias barteri
Anubias barteri var nana
Ammania senegalensis
Barclaya longifolia
Echinodorus bleheri
E. quadricostatus
E. tenellus
Hygrophila corymbosa
Ludwigia mullertii "Red Ludwigia"
Microsorium pteropus "Java Fern"
Rotala rotundifolia
Shinnersia rivularis "Mexican Oak Leaf"
Vesicularia dubyana "Java Moss"

... and probably a few others that slip my mind right now.
