I brought home two baby yellow Terribilis and put them in my 60x20x20. One of them immediately started snooping around, but the other did not start for a few minutes. Also, the larger of the two is a demon, climbing up the tank walls, jumping all over the place, exploring everything, while the other is hiding under the bromeliad. Is something wrong with it? Or is this normal, and the other one just extra-bold?
