They could just be twins, I'd say! Haha,

This is my fourth ornate, and first brown one. And I was surprised at his temperament! I know he's the most ravenous frog I've ever had, but I much prefer to think of him as constantly extremely enraged because it's more adorable. Maybe being brown just predisposes you to be vicious :] He lunges angrily at ANY movement. Even if he sees you standing across the room through the glass. He puffs up ready to lunge. So maybe he is a bit angry after all. Haha.
