[Gecko] Gravid Gekko Vittatus

[Brad Blackburn]

Ok, I can tell for sure that my Female Gekko Vittatus is gravid he stomach is HUGE and I am so happy that she is gravid but i think i have a problem. I have a repti-rapids Waterfall (made by zoomed) and they can get behind it because it was made strange and doesn't go in right angles like it should but I still like it and i am scared if she lays the eggs behind the waterfall when they hatch they will fall in the water holder for it and drown, how do i keep her from laying in it? also i have a fake plant in the middle that i made it look like a little bush (THEY LOVE IT!!!) will she lay in that? also i need to put plastic over the eggs with papertowel around them right?? please give me all the info i need this is my first species of geckos and my first set of eggs.. also how do i tell if they are fertile??   Thanks a ton: Brad
