I experience clutch sizes from 70-140. I utilize ten gallon tanks for breeding only as this makes egg collection easier. I find that they prefer a substrate of 50 cent piece sized polished river rock for breediung and egg laying.
The adults are oophagic, meaning they will eat eggs, so it is wise to remove the male as soon as egg depositing begins. Once complete, remove the female. (I see egg laying lasting 3-9 days.) I observed egg-eating primarily from females that didn't lay the clutch. (I theorize this is a type of reproductive interference, but my observations need a few more years of study to pan out.)
I carefully harvest eggs and rear them in groups of 35-50 in plastic tubs, increasing the size and water volume of the tub as they grow. Once they get near morphing, they are moved to ten gallon tanks with cloth mesh tops as kaiseri juveniles are excellent climbers and escape artists.
For housing I keep males separate from females, 3 per 40 gallon tank. These tanks are minimalist, consisting of many rock hides both above and below the water line, arranged in such a way to easily control the water level seasonally.
