Been into fresh water since I was in my early teen, having wide variety of fish and tanks. Oscars, tilapia, piranha, fancy guppies, etc. currently I am in my late 40's and have a 55 gallon cichlids tank, a 46 gallon bow front common fish tank and most recently (almost a year now) a 125 gallon mixed reef tank. Salt water is very VERY addictive. I found this app in the app store and love the fact that I can pick up iPad to read forums.
