How far along is she? A digital scale would come in handy. I had a guy tell me on here within the last week to expect a female to gain 1-2 grams a week up until time to give birth. If I were you, I would start trying to find a source of tiny feeders ASAP. Fruit flies are the way to go (Drysopholia hydei). They are very prolific and very easy to maintain- almost no work. A 20 gallon would work out for you. Only thing about aquariums is they have zero drainage. Jacksons need 60-80% humidity, but you want good ventilation. If your just going to use it temporarily, it would be O.K. I have 3 baby Jacksons right now that are doing great so far. I have an ultra-sonic cool mist humidifier from Walgreens piped into their cage ($40). I had no idea my Jacksons was gravid, until I walked in and found babies. When I did, I realized that she had slowed down her eating and would sometimes refuse food for 1-2 day stetches about 1 month before I found the babies. That might be a sign she is ready to drop 'em. After she gave birth, her feeding returned to normal, so it's a good idea to take note of food intake. For the babies, use your usual UVB linear tube and a basking spot that shouldn't exceed 80F. Ambient temp should be in the low 70s. That's all I can think of at the moment- I'm sure I'll remember something as soon as I post. Xanthoman is a wealth of good info on here when it comes to Jacksons.
