So I've been reading and wanted to clarify my understanding on a couple of things. I know most people's answer to the uber frequently asked question of 'can I get different species of dart frogs for the same tank?' is a resounding NO. There are a few reasons commonly given and I am a little confused about some bits. One reason I see is the risk for cross-contamination of pathogens from frogs of different geographic areas. This makes total sense to me if the species are wild-caught, but is it still an issue in captive bred specimens? If they are born and raised in the same captive environments, on the same food sources and housed in similar setups, would they still carry illnesses unique to their species and contagious and dangerous to others? Two, there is risk of cross-breeding and hybridization which some people feel very strongly about. Would this be a relevant issue to someone who has no intention of breeding the frogs anyway? Also, couldn't this be avoided depending on which frogs you put together anyway? D. azureus could mate with other tincs, but could it mate with a Strawberry Dart or a Reticulated Dart? I was under the impression that is couldn't, in which case, what would be the concern in housing some Strawberry Darts with some Blue Darts (for the sake of example, and I'm picking those because I know D. azureus hang out on the ground for the most part and, if I recall correctly, Strawberry Darts hang out up in the upper areas of the tank more, which brings me to my next question-- though I could be mistaken about Strawberry Darts, in which case, substitute them for a different, more arboreal inclined species). Although again, if one isn't intending on breeding anyway, why would the 'risk' of interbreeding even matter at all? Three, following on the above, if you selected frogs that would consistently occupy different areas of the tank based on their natural inclinations, would it be possible to mix species? Anyway, the reason I'm asking is just that I was perusing another forum reading about dart frogs and it seemed like this issue was a constant hot topic, but none of the above questions which popped into my mind while reading seemed to be answered very clearly anywhere. So...I thought I'd ask here, since y'all are always so helpful. Thanks!
