Will new neon tetras survive for 2 days without heater?
I have a 10 gallon established tank with one betta and one mystery snail. My heater broke but a new one is arriving in two days. I'm supposed to pick up some neon tetras today. Will they be okay without a heater for two days?
Yeah, they do best at around 72-75 at any rate. The betta does best at around 80, so you do have some incompatibility issues, but nothing too terrible. They both like soft, acidic water.
As long as the water stays room temperature in the 70s, then yes they will be fine.
