Does anyone know the ideal and acceptable range for Sepia Officianlis? Also, for Bimacs?

My first common cuttlefish put up with temperatures over 80 degrees f. without apparent discomfort (originally hatching after being brought home in damp seaweed on a hot day). Have also kept them in an unheated integral garage through the winter - much longer lifespan of over a year.
High temps. may be detrimental to larger specimens because of reduction in oxygen dissolved in water?
Wonderful animals. :D

Also think that higher water temps make them a bit more skittish and likely to ink

Bimacs can be kept between 72-65 degrees F.
