The most difficult part about caring for them, in my oppinion, is simply having a supply of tiny insects on hand. Culturing fruit flies, ordering or breeding crickets and culturing springtails can be over-whelming to someone who is used to just running to the pet store every other week to pick up a few dozen crickets or mealworms. Other than that, their care consists of monitoring enviornmental conditions and the animal's health, removing waste from the cage and feeding just like with any other captive reptile or amphibian. I would recomend practicing culturing fruit flies before getting the frogs so you can find a method that works well for you before you have frogs to feed.
Dart frogs have been documented to live for over 20 years in captivity. It's more common for captive frogs to live somewhere in the 7 to 15 year range. I would recomend that your first frogs be at least 3 months out of the water.
There are an immense amout of different species and different color varients availible, more so than other types of amphibians. Different color varients are not necessarily different species. As you put it, they could simply be "breeds" or color morphs of the same species. One thing that I enjoy about collecting and keeping dart frogs is that the color varients that are availible are naturally occuring and not created by humans who have cross bred different frogs to bring out different color traits. What I have in my terrariums is what occurs in nature. Breeders generally write a price list with the species name first and then the color varient or type (if there are multiple ones for that species) in parenthesis or inside single quotation marks. Example: Dendrobates tinctorius 'Suriname Cobalt' The species name is Dendrobates tinctorius and Suriname Cobalt is the color form.
