I have kept Praecox at temperatures as high as 28-32C during our summer
months without any problems. However, they always seemed to be "flighty"
when anyone approached the tank. I kept them in a tank that was reasonably
well-planted, and yet a friend of mine kept his in a bare tank and they use
to be at the front of the tank all the time?

The other possibly cause could be velvet infection which often appears at
higher than normal temperatures. Velvet is also very difficult to see on
them - generally, the only way to tell sometimes is by abnormal behaviour?
