I got a group of three suspected male cobalts along with other frogs in a big mixed vivarium. I have been thinning out the group and moving them out as I set up appropriate tanks for them. I got the last tincs out of the leuc tank just in time since they've started breeding behavior now that they're not overcrowded. I'm looking at my remaining tincs now and not 100% sure both cobalts are male. I would appreciate some help from people with more experience. I'll post the confusing frog first and then the other that I'm pretty darn sure is male. He has a slighter build and more pronounced heart shaped pads.
