I recently upgraded to a 150. I am soooo happy! However, I am sitting here looking at an empty 32 Biocube and want to do something fun. I considered doing a Fu Manchu Lion OR a Valentini Puffer, but I am open to other suggestions. I am NOT putting corals in this one ~ they are all going in my big tank, so that isn't a concern. I briefly thought about Moon Jellies, but I do not think I am ready for that.
