For those in the hobby for a long time (like my 50+ years), we knew fish-only for the first many years. Then, when we learned how to keep corals, we stopped collecting all the "non-reef safe" fish. I went many years without those fish until Hurricane Sandy wiped out my 500 gal reef tank (mostly SPS). That tank sat empty for a year until I got over the shock and figured out how to clean it. But, anticipating the sale of my house in a few years, I restocked it with all those "reef un-safe" fish that I hadn't had in years! Wow, was that nice to have those fish again! I then realized how much I missed them! BUT... all those fish in a barren tank just made me think of a dead reef, much like I feel when I go diving now. I'm now back to my SPS. Here are some photos of my former 500 gal fish-only tank:
I know somebody will ask why I didn't have a generator....so I will mention that in 29 yrs, I never lost power more than an hour. I lived on a main street, across from a Rescue Squad, so my street was always first to get power restored. But with Sandy, I was out for 3 days. I did have 2 gasoline generators but couldn't get them running. (They were old and I foolishly didn't take good care of them). After Sandy, I bought a natural gas generator...(then moved 2 yrs later!).
