betta feeling better

Question
Hi, i just wanted to let you know my betta fish is feeling better i woke up this morning and looked at my fish and he was making alot of nest bubbles i left him in the same bowl i had with the led light i didnt put in the tablets for the water for a day or two and i fed him just enough to eat but not over load i think the reason he was acting that way was because the water temperature was to cold for him his bowl is next to where the window is but i close the window at night and in the morning when the sunrise is up the let the sun shine on the bowl to keep him warm.

Answer
Michael,

Be careful putting the tank near the window. When placed there not only does the water temperature fluctuate, it can actually get too warm and burn your fish, or too cold and kill the fish. The sun can be quite warm during the day, but at night it gets colder therefore changing the temp in the tank all the time. They need it to be 82 degrees at all times, never changing.

Glad to hear things are looking up for you and him.
