Err, I'm not sure. The warmest I've kept them on a long-term basis is about 82 F, 28 C. No problems even though it was warmer than reccommended, but 32 is a lot warmer than that, so probably not helpful.
I was hoping to get some to, and had the same question - I keep my discus at around 29C. Anyone else see any other problems with keeping them with discus?
