Here's my tank, it cycled for a month with the 25lb live rock, then I added 2 clownfish, unfortunately I lost one right away , but its been 10 years since I had a tank, and the tank I had then was already established and came with all the rock, coral, fish, etc. Soooo what else do I need? Do I need more rock? Do I need a background? Do I need blue light? (I'm not planning on having coral). I scrolled through hundreds of threads last night (when I definitely should've been sleeping lol) and learned or relearned lots, but there's still a few things I'm unsure about. Thanks for any help!
