I would like to know what you would call adequate space then....:?Most Definitely!
you've had a fair enough amount of people post their experiences and reccomend you a bigger cage so manouvering in there during maintanence is less of an issue. in my limited experiences with P. regalis, P. ornata and P. pederseni, poecs will tend to hide first unless really provoked by their owners. of the three i would say the ornata is the boldest though, and gave me a bit of trouble during rehousings as a sling.so back to the topic, would fully grown ornata suffer in 30x30x30(CM!) terrarium?
we have no idea about your competency as a keeper, so asking if as a beginner if this is a good idea, people will probably say "NO". as said above they can be extremely fast, defensive, and potent.and what about whole idea? is it ok to keep p. ornata for myself if i'm a begginer?
