Thank you for your comment! I did do my research before purchasing my little froggies and am aware that they thrive in different conditions however, the owner of the aquatics shop which I purchased them from assured me that they have been climatised to 75F. So I have kept them at a constant 75F for the past 3 years and they seem happy enough (I hope)! It would be a shame to seperate them at this stage just because literature says they shouldn't live together. And I am not sure why my xenopus has never attempted to eat my dwarf but as you can see from the pictures in my albums, they are pretty friendly! Which although strange, it's also very lovely to watch grow up together! And I sincerely hope that my dwarf will never become dinner.
