ok so, i have an aquarium that split into 2 so as to not stress my bp ( I got a really good deal on it but it was way to big for a baby) but felt there was a lack of floor space on her side and I also saw her pressed up against the separation on the cool side (80F) one day so i deiced to cut a whole (its mdf so worries about splinters) and thought if she really needs it she use it which she is when she's awake at night other than that she sleeps on the warm side (88F)above her uth, but now im worried that it may be too cool over there (75F). will she really choose the right temperature for herself?

to give you an idea...
