I had a freshwater tanks on and off for years, never considered saltwater because I thought it would be too much work and too expensive.
Then I went on the tour of the Ocean Rider setup in Hawaii, where they raise captive seahorses and sell them directly to hobbyists (unfortunately not to Canada
I was amazed by the seahorses and the idea of getting captive bred really appealed to me. I came home, sold my freshwater livestock, and converted to my current seahorse species tank! That was only about six months ago, so I'm still a newbie! But I'm loving it...
