Hey Terry,
Yes I know how difficult keeping a SW tank is, and I am definitely not going to do anything where I dont think I'd be able to keep a living thing alive. It's definitely a long term hobby and introducing a single fish may very well be a few months in the making. I have a few friends who have aquariums/work with aquariums and have done months of research so I fully understand the risks involved in starting (and keeping) a FOWLR or a very basic reef system
Pretty awesome that you have wild turtles living in your dams though!
