I couldnt really say, as it was naturalistic I didnt want a large rubbermaid container in there messing up he look. I had about 3-4 inches of substrate, a bed-a-beast soil mix, and about 4 or 5 plants in there, one was a potho that grew like a vine and covered pretty much the entire bottom of the tank. A large hollow piece of bark that the female liked to hide in, as a few silk plants placed a little higher in the tank to fill in the spots that were lacking in color. One set of eggs I found at the base of the large hollow piece of bark. Another set was found at the base of the ground covering pothos, and the third was found along the back wall of the tank. All three sets were buried a good inch or 2 in the substrate. Probably the reason I never found them before when looking.
One of the three sets looks like they were the victims of crickets... the other two sets look healthy, with one set rather large. Almost as wide s they are long, making more of a perfect sphere than an elongated one. Hopefully they hatch soon. Ive never hatched crested geckos before so Im not sure how big the eggs get before they hatch.
Ive now set them up with a less than naturalistic vivarium with a laying box and what not, dont want to lose anymore eggs to crickets. Good Luck.
