Animal hybrids is a sensitive subject that seems to involve prejudgement and emotional responses/discussions. Just go back to your post and read the words: "feeble..hatred" and will see what I mean. There is nothing wrong with guns... I mean hybrids

. It's what humans do with them!
With luck and genetic knowledge, humans can develop attractive animals by selectively crossing some species! Complications arise when the hybrids result fertile and the race to develop a "masterpiece" also generates thousands of lower quality offspring that must be culled... but usually are not. They flow into the market and the big problem is; are usually offered as true species contaminating it's genetic pool. Other times the breeder will not be able to market them and not willing to cull them... will release them in the wild, thus creating another set of problems.
If unlike "Fantasy" frogs; the Dart hybrids can reproduce, it's a real problem to the true species and a valid reason for Dart frog fans to be against them. What you do is your decision, but I hope at least now you can see the dangers an improperly managed breeding hybrid poses to the natural species populations. If someone wants to defend the later, even if they sound "feeble and full of hatred;" they are in their right. My recommendation to you is to keep true species and enjoy the gift mother nature has bestowed upon us.
BTW, I've kept and bred Central American cichlid hybrids for 10 years. They are very popular across Asia (where they originated) and have a small but aggressive support base in the U.S. Still have 3 adult males and after they die, it will be over for me and the ever changing Luo Han! Good luck and have a nice weekend
