About a week ago i bought two fire-bellied toads and theyve been doing fine in a ten gallon tank so far...ive treated the water with dechlorinizing solution and ive set up a terrarium with half water and half lad (gravel, then moss substrate with a little cave..) i've noticed today that one seems perfeclty fine and has his/her's bright green coat with black spots while the other one's coat has become a much darker green coat...could it be because he is shedding? or is he sick? please reply back asap so that i may quarrantine him if he is sick...Thank you!
