I'm setting up a new tank for my betta and wanna make sure I get it right. What's the minimum size you'd recommend, and are there any specific features I should look for?

A 5-gallon tank is the bare minimum, but bigger is always better. They need space to swim and explore. Make sure it has a gentle filter, as strong currents can stress them out. Also, a heater to keep the water at 78-80°F is essential.

Yeah, I'd second the 5-gallon minimum. My betta was way happier when I upgraded from a 3-gallon. Also, avoid sharp decorations—they can tear their fins. Live plants are great, but silk ones work too if you're not ready for the maintenance.

Yo, don't skimp on the tank size. My dude was miserable in a tiny bowl till I got him a 10-gallon. Now he's living his best life, zooming around like a little king.

Thanks for the advice, everyone. I'll go for a 5-gallon with a gentle filter and heater. Any recommendations for substrate?

For real, bigger tanks are easier to maintain too. Less chance of ammonia spikes.

Sand or fine gravel works well for substrate. Just avoid anything too rough. And make sure you cycle the tank before adding your betta—it'll save you a lot of headaches later.

I've seen some fancy tanks with built-in lights and stuff. Are those worth it, or just a gimmick?

Depends on what you're going for. If you're doing live plants, good lighting is key. Otherwise, basic LED lights are fine. Just don't go overboard with the brightness—bettas prefer dimmer environments.

I'd avoid anything too flashy. Simple and functional is the way to go. Focus on the basics first—tank size, filter, heater. You can always upgrade later if you want.
