So i'm setting up a 10 gallon to house 4 male bettas, so each guy will have a nice 2.5 gallons to himself and maybe a few shrimp.
My only question is how to filter it? I understand the dividers allow water to flow through them, but if i have one filter for the whole tank won't the betta in the section with the filter be in like...a whirlpool?
or will the dividers allow enough airflow for one betta to just have more current than the others, but for them all to have some current?
Also for dividers, i'm not sure if i'm gonna make my own or just use the pen plax ones made for 10 gallons
