Hello, I'm building a 3 gal Betta + plants tank. I would like to know what would be the best filter for this tank. Should I follow the 10x the volume rule for the gph? I've heard that Bettas dont like too much movement in the water so I'm worried that a filter like this might stress him out. What do you guys think?
Can't go wrong with a sponge filter and an air pump! This is what I've used the most: https://www.amazon.ca/Uxcell-XY-2830-Aquarium-Bio-Sponge-Filter/dp/B00KZJYC9G
