D. Auratus and M. Aurantiaca

[Kurt]

Eight frogs of one species would be best. The two species you mention are of two seperate families and locations. Most dart frogs these days are captive bred and are usually parasite free. Mantellas, however, are still wild caught and are likely to be carrying gastrointestinal parasites, so you risk infesting your darts with an exotic parasite they would not normally encounter.
As most people know, most captive bred dart frogs lack the toxins of their wild counterparts. Wild caught mantellas are toxic and their presesnce in the same terrarium will most likely poison the darts. If you end up getting wild caught auratus, then they can poison the mantellas too. This is the number one reason why we do not house different amphibian species together. You would run the risk of losing both populations.
Lastly, where are you finding golden mantellas for sale? I have not seen one offered in years, which is too bad cause I wouldn't mind having them again.

That's what I wanted to hear! Thanks. I didn't know that some of the Mantella's are brought into the market from the wild. We'll have to break it down to one than!

Thanks

Yup, personally I would go with captive bred darts and if its auratus you want, I like the Ancon Hill and blue morphs. My favorite darts are the tincs or tinctorius.

[brikag]

I hear that a lot from the people at the pet store and their customers about the Tincs. Why is that? They say they're easy to take care. What's your take?

[Kurt]

They are easy to care for, relatively speaking, they are largest of the dart frogs, and I personally think that many of them are just stunning. Some of my favorite morphs are Oyapock, citronella, azureus, cobalt, and powder blue. Look in the FS section as Lisa was selling some.
Auratus usually don't do much for me, they are just black and green for the most part. Tincs on the other had have various shades of blue, yellow, white, and black depending on what morph you have. I have a single azureus.
