I figured that is what happened lol. I just wanted to make sure that when you researched them.. you were indeed researching the correct ones

You will want to get on a routine for making the cultures. With 3 frogs... you may want to try doing 1 culture per week. You will most likely end up with an excess of flies.. but it is better to have too many than not enough! That will give you an idea of what culturing schedule would work for you. Sometimes cultures can crash for the strangest reasons. By making a new one weekly you would still have enough from your previous cultures to feed from. Always start your new culture with flies from your youngest culture. There will be less of a chance of transferring mites that way. Mites are one of the things that can destroy your culture! You could invest in some mite paper to sit your cultures on, or you can make your own with paper towels and a mite spray.

As far as supplements go.. dart frogs need a calcium supplement with their feedings. I personally think that Repashy Calcium plus is the best.. but that is just my opinion. Supplements are only good for around 6 months.. and would need to be replaced after that. There is no need to buy a large container of supplements when you will probably end up throwing most of them out. I also give a monthly dose of Repashy Superpig to my leucomelas for color.. but I don't know if it would make a difference with Azureus. I occasionally do a dose of Repashy Vitamin A once per month as well. Calcium plus is a great all in one supplement.. so many only use that.
