The temperatures that I am faced with are accompanied by very low humidity.

I have been having lots of trouble with lillaeopsis and some other type of
grass plant that I forget the name of.  Is there a correlation between growth
of grass-type plants and temperature?

I have noticed that my harlequins have developed a very attractive red tinge to
their bodies and particularly tails since I moved to this area.

Steve.  Sorry if anyone else has responded to my original post, but one of my
e-mail accounts has apparently stopped working.  Hopefully, I will be able to
catch up when it returns!
