I do.. https://forums.saltwaterfish.com/t/322410/puffer-nano-diary
I have a Green Spotted Puffer that has been in full marine for a few months and I gave him his own tank. It's FOWLR I have a Chalk Bass and Engineer Goby in it also. I was thinking of an alternate stock list that went like this. Green Spotted Puffer, Chalk Bass, Snowflake Eel. In the end though I thought an eel would just be so boarder line cramped that I thought engineer gobies a totally better alternative. I was also thinking of a Frog or Scorpion Fish. I didn't want to do a reef either and I am glad I went with this setup. It is unique and I think I will have a lot of fun with it. I was like you though, wanted a nano but not the run of the mill nano. My thinking is, if I am going to sink that much $$$ into a tank with all those corals, it will be a big display tank with some awesome fish. Hope that helps and keep us updated
