I moved him out of a false bottom setup (24x48x24) five days ago, after discovering mold on the underside of the potted plants. Both frogs were inactive for about a week before that which concerned me, so I switched back to the water setup they seem to thrive in. I saw the dots when I placed him in the new water tank and watched a few days to make sure they weren't just from a change in environment. There's less dots now than before, but they aren't going away completely. He is moving and eating, the only issue is the dots at this point.
