Hey, I would really like to start out a vivarium with some leucomelas as they have always been my favorite frogs as a child and I've read they are one of the more 'easier' to care for out of the darts. I was considering a exo terra glass terrarium 45x45x60 which I know will be a suitable size. I would like to know:

1. What changes would I need to make to the terrarium? ( to make it safe, and prevent fruit flies escaping)
2. What is the best way to maintain the correct temperatures of mid 20's (24-27) and the most efficient way to maintain humidity required?
3. How many frogs is a safe and suitable number to keep to reduce likeliness of disputes and retain happiness?
4. What plants are suitable?
5. What lights are needed and are heat pads/lights needed?
6.How often do you recommend a full clean out etc besides spot cleaning?
7. How often do you recommend the frogs to be fed?
8. What drainage mechanism is the best?

Thank you for your help and time, if i think of anymore issues or questions I will respond with more. Or any advice will be grateful thanks
