Went from 7 fw tanks (sm to med) that required almost no money or effort to 4 sw tanks that require most of my $$
& time (mostly because I'm a beyond-help addict). When I did fw, I could save lots of money. With sw, I now spend waaaaay too much every month.
Just in the last month I've spent well over a grand to upgrade the new place with 2 big tanks. And yeah, we moved to a bigger place so I can have bigger sw tanks. I guess that's proof of my insanity/addiction. Fortunately, my wife likes both new big tanks.
At least now we're almost neighbours, eh Xtasia (1.5 blks away).
Also, I've almost never heard any sw people say, "Hmmmm, one day I'd really like to try a fw tank." (prob. because that's how they started with fish) while I always hear fw people say, "Wow, I really have to try sw one day."
And in terms of prices, have you seen how much fancy Arrowanas are going for on the BCAquaria board.
The only thing comparable in price would be species like Hawaiian Dragon Morays.
Bottom line, I vote for sw as more addictive.
