Hey Guys! I'm new to this website. I joined so I could get some advice for my newest tank. I have two other tanks (20g and 55g) and I loved them so much I bought a 36g bowfront tank off a friend. I have been cycling this tank for about 3 weeks now without any fish but have been using fish food as my ammonia source. My ammonia levels and nitrites have already peaked and are coming back down, so about one more week until I can add fish. I was wondering about some ideas I can stock this tank with. I am really interested in having a semi-aggressive tank because I really want a rainbow shark as my centerpiece. I am open to all ideas, but I do want a lively tank with atleast one "bigger" fish (somewhere around 5" to stand out). My other tanks are community tanks and I want to mix it up. Thanks for your recommendations ahead of time!!
