I am finding conflicting information as to what temperatures bettas can thrive in. I am finding 78-82 degrees mostly and people freaking out if their tank hits 84 degrees.
Part of my plan was to have outside ponds full of betta for my own enjoyment. My breeding area is inside my garage. I live in Florida and the water temp outside on a summer day in the shade reaches up to 87 degrees. Water in my garage goes from 82 degrees overnight to 85 degrees during the day. It doesn't fluctuate any more than that even on the hottest day because of the concrete block construction and my house is under a giant oak tree. I looked up the info for Thailand and their outdoor temps are nearly identical to central Florida.
In this part of the country most pond owners use small fountains to regulate summer temps.
Is this even going to work out for me because my fish are going to have to deal with higher than recommended temperatures?
