I recently purchased two fire bellied toads, the second day, I noticed one of their eyes was bulging and black. The day after, I realized that the other one of the other toads toad's eyes was was also bulging and black. Otherwise, they seem very healthy. One is extremely active and is always climbing things and the other spends most of his time in the pool. But it does concern me that their eyes are like this.........any knowledge of what this could be would be much appreciated....I have tried in vain to research this on the computer.
