Welcome tee!
your fish look very healthy.to cool my goldfish in summer i have a fan that is on a timer aimed at the water surface,seams to help with cooling.
i usually freeze bottles of water and add them, not needed to do it yet this year!!. tank and fish look really good love your black fantail is that an oranda?? i have a chocolate colored one.

I thought they were overcrowded ? until I saw the other half of the tank was empty and as you say you have had them for years (and they look outstanding) so carry on doing what you have done in the past (works for you why change it)
