My African Clawed Frog had been housed with my betta for a while until I got him his own tank. He's now in his own tank, but the betta tank was kept at 78F. Now, I moved him to the new tank, which was reaching up to 80F. So, I began cooling it with a fan, which has brought it down to around 70-73F depending on the time of day. Will he be OK with such a sudden water change in his environment? Looking at info, they are cooler water frogs, so I'm hoping it will be.
