Sorry to hijack... How does one go about getting them to eat fruit/veg? Mine won't touch it, they'll sift through a whole bowl of greens and throw it all over the floor without eating any of it. I've tried just about every kind of vegetable I can think of too, but they won't have a bar of any of it.
Also, to the OP, whether it's right or wrong I don't know, but I've got quite a large tank, it's about 5 foot high by 4 long and about 1.5 wide, half land and half water, and being all glass it would send me broke if I heated the whole tank. I've got 2 basking spots, 1 up high and one at ground level, both with a 50 watt globe running on a timer, which creates basking spots of 32-40 (1 of the spots is over a floating turtle dock as I've also got a turtle in there, and the water evaporates fairly rapidly, so it depends on how close the light fitting is to the dock at the time.) I've also got 2 uv fittings, 1 4-foot tube on top of the tank, and 1 aimed at the same basking point on the floating dock (because the turtle can't get all the way up to the top of the tank
) I've also got a 15watt head cord buried in the substrate for those cold nights, but they don't use it at all.
In this tank I've got the turtle (palm sized, not fully grown), 2 water dragons (1 missing bits so not very mobile, both around 5ish inches svl) and a juvenile mertens water monitor.
I'm in the process of re-furbing the tank, so it will become all water at the bottom with a 1.5-foot ledge with substrate, plus all the climbing branches.
