Hi,
I am going to buy an Ahaetulla prasina in a couple weeks, and now I'm at the point where I need to get as much useful information as possible regarding the species, unfortunately is hasn't been so easy to get the info, I've already got the growing parameters(temps and humidity) and some basic requirements, but each piece of information I read only brings me more doubts.. So for now I got these questions, and I hope you guys can help me answering them, I also would like to know some experiences with this snake form the ones that grow it

.
I have read that they need to be feed twice a week, is this true?
How big should be the food, I mean, they are very slender snakes so I guess food musn't be wider than the body of the snake as it's done with Corallus boas, right?
I have understood that they need UVB light, but also read that vitamin D sumplements are needed, is this a must?
And as for the temps and humidity, I have read that about 80 to 95° degrees(80 for the cool spot and 95 for the basking spot) and a humidity of more than 80% are good, could you please correct these parameters in case they are wrong.
Well, for the moment, I think those are my doubts, eitherway any extra info would be super accepted!
Thank you.
Best regards,
Abiram
