my tank is a45? 36L X 12W X 24 tall it was given to me and i have had freshwater fish for 2 years and decided i wanted to change. I am using this as a starter and hopefully will move to a bigger one within a year or two. I would just like some soft corals and mushrooms and an anemone. W would like to keep the cost as low as possible because i am going to move on to a bigger tank. I am using this tank as my learning curve and to get my feet wet. So I will not be embarking on exspwnsive corals. Just a few to learn about upkeep.
