Hi! I’m considering getting a betta and I currently have a 20-liter tank, which is about 5.3 US gallons.
I’ve been reading different forums and Reddit threads, but I keep finding very different opinions. Some people say 5 gallons is perfectly fine for a betta, while others recommend at least 10 gallons.
I really don’t want to get a fish if the tank is too small for it to live comfortably and thrive. Would you consider a 20L / 5.3-gallon tank appropriate for a single betta if it’s properly filtered, heated, planted, and maintained?

5 is fine, 10 is better. Honestly, if you get a 10, you’ll even have people say, “Why don’t you get a 20?” You can never really do good enough in some people’s eyes, but as long as your care is good you’re fine.
For a long-finned Betta it’s completely fine, for a female or short-fin I’d advise to get a 10gal. Just remember that the smaller the water volume, the harder it is to keep stable water parameters.
I mean 5 gallons is perfectly fine. When I still had my Geoff, bless him, he still used his entire 10 gallon tank as a longfinned male. I’m not saying 5 gallons is bad or anything, but I personally wouldn’t do a betta in anything under a 10g.
