My fishroom is self contained. The heat from the tanks heats the room. I
do use heaters in every tank, but the room is warm enough to don't come
on very often. When I started going bigger, I only had a 30k a year income
to do it on, and I have 4 kids. I bought used tanks, used gravel, whatever
else I could find cheap. I resealed old tanks, I made my own lids, and to
this day I don't bother buying aquarium strip lights. I use cheap Walmart or
home depot undercabinet flor strips. I have some older strip light that used
the incandescent bulbs, I put in the little flour screw ins now. I save alot
on power that way. I painted my main fishroom glosswhite, so I don't need
a whole lot of light to make it bright. I made all of my own stands out of
wood, I made all of my own ponds out of other materials my partners
business has access to. I buy cheap slate, clean it up and cut to size,
make my own 'furniture'. I buy large packs of everything, food and
chemicals. As far as fish go, I shop around but I try not to be too cheap,
because you get what you pay for. I buy from breeders when I can, or
stores I know and trust. Buying good stock is not cheap, but they are
more likely to do well. One of your best investments, is knowledge. If
you get the basics down and you know what you need and how to run
the tanks and look after the fish, then when you get around to the buying
the fish part your investment is protected. Saving money is easy, but you
have to know what you are doing to make it work well.
