Betta Tank Upgrade Advice

i want to upgrade my betta to a 2.5 gallon tank so he can be happier and healthier. I was wondering if it was possible to put a filter and heater in the tank, and if so, which ones? I was looking at these:

Would they work? Thanks.

I don't see why they wouldn't work. I have a similar filter in a 1 gallon of mine and depending on your room temperature, you might not need a heater.

I have my betta in a fluval edge 23 litre it's perfect for him it comes with a built in filter, I got a 20 watt heater of eBay and it keeps the little fella happy. It's my favorite tank now!

Heaters are good if there is going to be any temperature difference - you want a nice and stable temp for your betta!
 
 
Those look great
