Recommend for a group chorus

[Tropicok]

I've looked at dart frog care and description pages until I'm cross-eyed and confused. I'm asking for recommendations for a group tank of frogs that have nice calls. I like the bi-colors canary-like song but not crazy about their looks.
Thanks, Alice

I like the call of Phyllobates terribilis. The mint phase ones at Black Jungle are always calling when I go there.

I looked up frog calls and I like the D. terribilis and the leucomelas. I'm beginning the larger tank and think I will let it mature until I can afford about 5 or 6 of whatever I decide on. Thanks for your advice.
PS: drove my auratus crazy playing their call. LOL

You're welcome.
