Hello everyone I would like some help with my first nano tank. I'm going to ask newbie questions so be patient. I just got a 2.7 gal. Tank and am looking to fill it. I would like it to be planted, so what "gravel" should I use for the bottom. What plants are best. What fish could I put in it. What light should I use and lastly, heater or no heater (if so which one). Thank you everyone.
