Hi Hugo,

How do you get on with the high temperatures in the summer in
Portugal? Do you cool your aquarium or do the inhabitants manage to
withstand them? Some of our British animals come from warmer waters
but some of them come from the north and are near their southern limits
especially in the summers that we get nowadays. Even tropical marine
tanks can get over heated. I am expirimenting with various cooling
methods but have not come up with a surefire solution yet.
