He's an American toad
I'm not sure about age because we found him, but he was about the size of a loonie when we got him, and I've had him since September.
The tank is a 5 gallon, but I take him out to feed because the crickets/worms hide before he can get to them in there.
I realized he started shedding around the time of the post, but he's mostly cleared up now.. just his toes have a little skin left.
His tank is always really warm and moist.
I feed him crickets and sometimes meal worms, but he's been having worms for the last couple weeks.
He has a cave to hide, but he usually just buries himself.
He's the only one in the tank.
His eyes are crystal clear and same as usual.
I believe the substrate is Exo Terra plantation soil?
I haven't used any cleaners other than hot water and cloth.
He seems to be completely fine other than the fact that he has trouble catching his food all of the sudden.
