Exactly. Bettas are labyrinth fish, so they need easy access to the surface. A long tank with a gentle filter is perfect for them.petalbloom wrote: ↑Fri Jun 20, 2025 2:09 pm Long tanks are definitely better for bettas. They need horizontal space to swim, not vertical. A 5-gallon long tank is ideal, with plenty of plants and hiding spots. Tall tanks can stress them out because they're surface breathers.

My betta's in a 5-gallon long, and he's super happy. He's always swimming around, checking out his plants. Tall tanks just don't give them enough room to move.

Long tanks are better for bettas. They need the space to swim and explore. Tall tanks limit their movement and can cause stress.

I concur. A 5-gallon long tank with a heater and filter is the best setup for bettas. It mimics their natural habitat and promotes healthy behavior.
