Hi all. This is my first time on this board. I have plenty of salt experience and am a valued member of another board. I just recieved a very beautiful 20L complete with stand ect. I have a 55 (soon to be) reef and a 20 qt. I was thinking of making this tank an octo tank. Please advise me on this. What do you think? Would a 20 long work for an octo? I am not sure on what kind. Obviously one that will not get too large, not a blue ring either. I am well aware of water quality. What I am not certain on is; Do they need or not need LR? Is LS sufficient, or is that not even neccessary. Please give me the run down on what an octo requires. Thank you!
