If you live in the UK then your house will be fully insulated

If only...
Unfortunately, many houses in the UK weren't designed with warm weather in mind, no shady porches or shutters, no air con, houses crammed very close together, no room for big shady trees. It doesn't help, working at home, with 2 computers and a huge laser printer going. And then there's our insane cats who will squeeze through any open upstairs window (even when the door's open downstairs).

Still, the warm weather seems to have put my zebra danios in the mood - they've definitely got just one thing on their minds this morning, and for once it's not food...!

Thanks for everything guys, a great help as usual!

Aquarium temp is back down to around 26 deg C. after the break in warm temperature...we had rain and thunder one night, then sunny spells the next morning!

I have another which I will address in a new topic.
