Betta Fish Bowls, Habitats, and Accessories
I'm looking at starting a 5-gallon setup for my new betta. He's in a 1-gallon until I can upgrade. I'm doing daily 100% WCs. He was given to me, so I had no time to prepare!
What is a good filter for a 5-gallon? Do they even make them that small?
Also, what is the smallest adjustable heater...
