but DOS what is the ambient temp of you house ATM? 16c? 19c? unless you can make sure the water stays cool enough then fish/crabs/nems will perish after prolonged heat exposure. take the catalina goby for example, it comes from temprate areas of the US and whilst being able to survive in tropical conditions in doing so its life cycle can be reduced by a half!
high temps may not kill over night but they can reduce your tank mates lifes by massive amounts.
