I have a male and female Chilean Helmeted Water Toads and I am struggling to find care instructions....mainly temparture of water....heater or no heater?

I'd look into their native range temperatures yearly.

I've heard anecdotally that they experience cold water temperatures and begin to experience stress and die off at higher water temperatures. Think temperature ranges of 50 to 70 degrees Fahrenheit.
