Alright, right now i have 6 black neon tetras and 3 peppered cory's. I know i might be totally pushing it if not over stocking, but I have really been wanting a male and female pair of Apistogramma Cacatuoides Triple Red, Double Red, or Orange Flash. Depends on what Aquarium Adventure has in stock. basically as the title says, i have a 12 gallon tank with a decent amount of plants. Is it possible to add them and they will have room? its up to you guys because i have absolutely no clue. I also might get a 20 gallon tank for christmas, depending on how convincing i am with my parents. We'll see. Thanks in advance.
