I put a spare jaeger in with the acara. Chill continues to improve and is moving his fins more. Checked on him an hour ago and he was resting ok. Just glad I didn't lose him too.Sorry for your loss
I would look into Ehiem Jagger heaters. When I first got back into fish keeping I got cheaper heaters and all failed within six months. I switched to Ehiems and two plus years no issues at all. Also look at inkbird controllers, they add another level of safety.
