Who Gives A Fish Forums

My betta's in a 5 gallon with a sponge filter and a 50 watt heater. It's been running smooth for months, no problems. Just make sure to cycle the tank properly first.

Yeah, cycling is key. I rushed it once, and my fish paid the price. Now I always test the water for a few weeks before adding anything live.

It's so rewarding to see them thrive in the right environment. You're making a great choice with the 5 gallon. They'll thank you with their vibrant colors and active behavior.
