redeyes croaking a lot

[Gomugomuking]

I wish mine croaked through the night. My male croak when he wakes up, and when my alarm goes off in the morning, with an occasional croak or two in between. Maybe if I add another male to the tank.

Mine have two different croaks so I am pretty sure the bigger one is a female and the smaller one is male. They talk to each other all the time! I had the female (Kiwi) first, and she never croaked. A few months later I got the smaller guy (Gingernsap) and the night I brought him home he croaked all night. They were in separate tanks, however. But I bet they could still hear one another, and after that night all they do is croak! It's so awesome. I have them in my bedroom and they only really start croaking when I go in there to go to bed. Since I got the O.K. from the vet that both frogs are healthy to put them in the same tank they have talked so much more
I love my little guys <3

Thanks for the quick responses. I am glad it is (possibly) a sign that they are happy.
I clean out their entire viv once every month, so they darn well better be!
