Congratulations on your new pets!! I hope you enjoy them! They are wonderful starter amphibians in my opinion. Also, I have two fire bellys as well and I have them in a 20 gallon long with half land, half water with gravel and some fake plants, plus a filter in the water section. Mine seem to croak a lot too even when they are not hugging each other. I think they are just talking but I'm not to sure. I had my fire bellys for a couple of months now and they seem to croak a lot and to me it sound like their barking. So I would advise not keeping them in your bedroom, I learned that the hard way. I also never ordered any living things online, I think its because I live in a city and I have the three biggest pet store chains near me, like Petsmart, petco, and even petsuppliesplus. And please don't start that big argument over the way those store treat their animals, I heard enough about it. Silkmoth, I hope you have a wonderful time caring for your new amphibians. I know I sure do!!!
