I’m moving my betta from a 2.5gal to a 10gal. I realize the 10gal might be too big for my desk and might go to the dresser. That being said I would like to still use my 2.5gal. I’ve seen people make terrariums using twigs and dirt and stuff from local ponds or rivers and also the water too. Would this be a good idea to do with the 2.5gal? Or does anyone have any other ideas?
