I've kept tincs & auratus years ago and I want to get back into dart frogs again. I've seriously been considering D. t. 'regina', or terriblis. On the other hand Thumbnails are incredible for their size. but I have no experience with them. I understand I'd feed primarily fruitflies and springtails. I'd keep bwtween 2-4 thumbnails. I havent choosen a particular species yet. It's hard to choose just one but I dont have a large budget to get started with. Any insight on the care of these lil jewels would be greatly appreciated.

How often do you feed them, daily, every other day?
How long does a culture of fruit flies last ?
How many cultures would you go thru in a month?
