First off, thank you all SO much for the help and fast replies. What an awesome online community. I use a large heat pad under approximately a quarter inch of coconut mulch. Temperature sits between 89f and 92f. And it is certainly possible she was underfed prior to my purchase, the "breeder" I bought her from seemed kind of sketchy.....I'm glad what she is doing is normal. However I'm unsure of what is meant by the sides of the tank being "covered". Should it have the graphic stuff that goes around fishtanks or just covered with fake plants? At this point, none of my sides are necessarily covered....
