I'm going to buy some baby piranhas for my aquarium and I definitely will buy a heater .I'm wondering what's the minimal temperature for piranha tank.Can I turn off my heater if temperature is 62 + becouse in my country there are only 2 or 3 months in year that temp drops below that.I will put a thermometer if temperature isntn good I will put the heater in the tank.
What is min temperature for piranha tank?

75 to 85 is their habitat range tank temp would be good at 78 or 80. So yes a heater will be needed. Do you have a filter?
The tank is outdoors? How big and what's it made of?
Where are you located? During those 3 cooler months, what's the day -vs- night temperature like? What's the average? IE is the night mid-60s but back into the 80s when the sun comes out?
I've found that Amazonian sp seem to be quite low-range tolerant, but nowhere near 60-odd for 3 months running as the warmer season. If the tank's indoors, then the average temp will be higher. Occasional overnights can work if your volume is enough to minimize fluctuation, or if it's a concrete or in-ground pond with plenty of wall-volume to hold heat. Either way I'll agree with,

, you will be setting a heater of some sort, possibly augmented with some sort of insulation for chilly overnights.
Alt.: build it, fill it, stock it with non-target or starter spp. and set a temp logger <https://www.onsetcomp.com> through at least the colder period to get an idea of what you're up against. Once you've got your variables, then decide on your piranhas vs costs of heat... or not, as you may well come to love your "starter" swordtails, sturgeon, gar, Texas cichlids, royal loaches & high-fin sharks
