This is very
stressful on any fish. That's why heaters are a must.

## There are no heaters in nature.

That's kind of a misleading comment, isn't it? "In nature" the size of the body of water acts to mitigate temperature changes, even in something the size of a small pond (compared to a 1-2 gallon fish bowl).

## To some extent this is true. I have two ponds (800g and 2000g) and the temp varies from day to night, and day to day by several degrees.

As long as bettas are kept over 72F they do fine.

I'd say Over 72F _and steady_, and they'll do OK. If your ambient air temperature is variable or consistently under your target temperature (as it always is in the fall/winters here in New England), then the heater is called for. If you live in a more temperate or tropical (or continually air-conditioned) climate, then it isn't a requirement.

## If I were in New England and had a cool house I would then have to do something about heating the bettas.
I just looked at the thermometer in the middle bowl. It's 74F.

They do make small, pre-set ones that have no thermostat in them. Not a
good thing because the temp will rise above the pre-set temp during the
day when a tank light it is, or the house warms up, etc. Again, you'd
have rising and falling temps.

## Which happens in nature. Where on earth does the temp stay the same 24/7/365? If varying temps were harmful my bettas wouldn't be living their full lifespans.

Rate of change matters. The smaller the body of water, the quicker the rate of temperature change.

## And bettas live in everything from puddles to flooded paddies. I have not had a problem with them not adapting to these daily changes.

As when a young child goes from a warm house to
the chilly outdoors when under-dressed; expect health problems to result from irresponsible care and rapid changes in environment.

## There are no rapid changes. Their bowls slowly drop in temperature at night, then warm up a few degrees in the daytime. They live an average of 4 years. You can't expect much more from a betta.

The significance
of this to fishkeeping varies significantly by geography and what the fishkeeper maintains as their ambient air setup in their home (which is why I suspect you and Tynk are "at odds" on this topic).

## I assume the betta owners or those thinking about getting one (or more) would have a thermometer and use it. If someone keeps their house at 68 to 70F then I would say that is too cool for a tropical betta or any tropical fish - they need a heater. I find the water in the tanks and bowls is always a little cooler than the temp of the room. Our house is on the warm side so even the platties don't have a heater. They too are thriving and reproducing.
