RE: any salt water aqurium hobbyists?
I have a 50g with some soft corals. Colonial polyps and some sarcophytons. Fish are a clownfish (lost the male last week), flame angel, copperband butterfly, and a royal gramma. Various hermit crabs. Ofcourse live rock.
It's a nice fun hobby but it's definitely a big step up over freshwater as far as maintenance goes. For instance if your fish get a disease like ick and you need to treat the tank with copper you have to setup a separate tank and remove the fish to it for treatment since copper will kill corals and invertebrates. But it's the only real way to kill off that disease. So a pain in the patoot. Also when you change water you usually dont want to use tap. You buy RODI water from walmart or you filter it yourself. And salt must be mixed in and brought up to the right specific gravity before you put the water in your tank.
Someday I'll go back to freshwater again to change things up and take a break from all the work. But the fish are gorgeous and the invertebrates are really something to see in saltwater tanks.
