I switched out my female betta from her 10gallon unheated tank to a 1/2 gallon. I put her in the small bowl with the same temp water as before 70F and than put in a hydor heater 7w. Over the course of 4 hours the temperature has risen to 80F which is what I always keep my other betta at in his tank. She's acting kind of lethargic and I'm a little worried it might have put her in shock. Is what I did okay? I assumed it was technically the same as floating a fish in a ziplock until the water reached the same temp as the tank. Anyway, I'm going to keep an eye on it and make sure the temperature doesn't get higher. But do you think she will be okay like this? I'm currently waiting for her 6 gallon to cycle, that's why I switched her out and I figured the heater would be more effective in the smaller bowl.
