Heater for 1 gallon?

[ryanjcalifornia]

I have a 1 gallon undergravel filter fishtank as my "betta throneroom" but i'm worried about my betta getting chilly. I live in so. california, so its not that cold of weather, just a lil bit, should I...

even worry about a heater?

Or if I should, what brand?

Also do you know of a light that would be small enough to work in that tank? It's a TopFin 9.99 undergravel filter tank, its weird shaped, but I like it, but I was wondering if anyone has seen anything online for something like that...If not, cool, I'm gonna figure out some kinda DIY project for that!

Thanks ya'll!

You probably don't need a heater for that size of a tank... especially if your house is at room temp or higher. Also bettas are pretty hardy considered to most fish and aren't very picky about water temp.

Good luck on your thrown room,
