PatrickB Posted April 2, 2021 Share Posted April 2, 2021 Hello, I'm establishing a small school of neon tetras and would like to get away with not using a heater. It's a rimless tank & without a lid is runs around 66f during the day and perhaps slightly colder during the night. I've acclimated them and after about a week they seem to be getting along just fine. They are active, hungry, and showing good color. My question to the group is for those who have more experience with these fish. Is this an acceptable temperature long-term? Thanks! Link to comment Share on other sites More sharing options...
