I have 6 fire bellied toads, 3 males, 3 females, 4yrs old. Ive had them from babies and have been happy and healthy, breeding so they must be happy!! Over the past few weeks ive noticed 1 of the males doesnt seem to be able to walk in a straight line, he keeps shaking his head and circling to the left, he does hop but not straight!! Anyone know what could be causing this?? He has always been the smallest of them all. Thanks. x
