So I live in Hawaii the temperature here is usually between 70 and 80 degrees Fahrenheit. I've recently gotten myself a betta and while I've had 3 in the past i'm still a complete newbie on how to take care of them. I've recently gotten a filter and was thinking of getting a heater. I asked my mom if i could mail it to her workplace seeing that i wouldn't be home for a couple days to bring the package inside and i don't trust people not to just let it sit there without opening it up. She told me there was no need for a heater since the temperatures around here are normally as i said 70 and 80 degrees Fahrenheit. My mom does know a little bit more about fish them me, but she is still not that experienced so i wanted to ask your guys opinion if i should get a heater.
