So i have a 10 gal tank with 6 pygmy corys and 3 olive nerite snails and i was just wondering if adding a betta would be overloading the tank. The tank is planted (i wouldn't say heavily because my corkscrew vallis is still making up its mind on whether or not to grow). The one thing i hate doing is overloading the tank so if i was able to add the betta but have it be on the limit of what the tank could hold then i probably would just not get the betta.
