I have kept P. guttatus and P.intermedius for about 10 years- but long time ago.
They are easy to keep. Just provide a tall setup with a fake rock backwall and rock piles with lots of mainly horizontal devices.
Hot and bright basking spots are a MUST. These days I would only use metal halides.
They eat the usual feeder insects but do not manage very large prey items. Also they do not need much food.
Sadly skittishness varies a lot between individuals. I had one pair, which did bask all day and could be watched well. Another pair was hardly seen at all in a neighbouring tank under the same conditions. Anytime, I entered the herp romm, they immediately vanished.
They do not make a good breeder project for a beginner.
From my experiences they only lay two eggs and not more than 2, maybe 3 clutches a year. My females never buried the eggs, but squeezed them into small crevices. Since you do not see any signs of gravidity in females carrying two relatively small elongated eggs, I NEVER managed to find the clutches in time. All eggs were hidden very well and dried out before I found them. Very sad!
So you need luck to find the eggs and even if you find all, you will never produce large amounts of babies.
But since Platysaurus are extremely colourful lizards, which are not difficult too keep and since all specimens in the trade are imports, I think EVERY breeding success with these should be great and a step into the right direction.
But again: Do not expect to produce many babies.
Also it is important to buy pairs from the same import. Females of the different Platysaurus species do all look VERY similar, so its not easy to find a female for a given male. You often would end up with mixed species pairs.
Hope that helps
