Aquarium size guide

[Bakero]

I'm setting up a new tank and wanna know what size would be best for a community setup. Gonna have some Tetras, Corydoras, and maybe a Betta if they can chill together. Tank's gonna be in my living room, so I don't wanna go too big or too small. What's the sweet spot?

For a community tank with those fish, I'd recommend at least a 20-gallon long. Tetras and Corydoras need swimming space, and a Betta can work if there's enough hiding spots. Just watch the Betta's temperament, some don't play nice with others.

yo, i got a 10-gallon with a betta and some neon tetras, and it's kinda tight. betta's cool with em, but the tetras seem cramped. gonna upgrade to a 20 soon. listen to dawnrider, they know their stuff.

Agreed. A 20-gallon gives you more flexibility and stability. Smaller tanks can swing in parameters too easily, especially with a Betta's territorial nature. Plus, Corydoras need a group of at least six, and they'll appreciate the extra floor space.

I have a 15-gallon with just Tetras and Corydoras, and it's working well. But if you're adding a Betta, I'd go bigger like everyone's saying. Better safe than sorry, right?

My 20-gallon long is perfect for my community tank. I've got Harlequin Rasboras, Pygmy Corys, and a super chill Betta. The length gives everyone room to swim, and the Betta has his own corner. Highly recommend it.

Just remember, bigger tanks are easier to maintain. Less chance of ammonia spikes, and you don't gotta stress over tiny water changes as much. My 29-gallon is a dream compared to my old 10.

Totally agree. Stability is key, and bigger tanks forgive small mistakes. Plus, more room for plants and decor to make it look awesome.

If you're gonna mix a Betta with other fish, make sure there's plenty of visual breaks. Tall plants or driftwood can help. And yeah, a 20-gallon long is the way to go for that combo.

Thanks for the advice, everyone. Gonna go with a 20-gallon long and take it slow with the Betta introduction. Appreciate the help!
