I found a 20 gallon fish tank at a thrift store for $7.99 canadian money. I was wondering if I bought this tank and bought the rest of the requirements for a freshwater aquarium, would it be cheaper than buying a whole set (starter kit) at a pet store of stores like Wal-Mart??

If it has a light canopy then I would say yes. But they can be the big expense when buying a tank.

A Wow thats a great deal! I'd first make sure it's water tight(you never know.) Walmart Canada has some good filters for pretty cheep, I like the wisper models they carry! Then you need a heater and gravel, temp gauge ect. So yes it'll definatly be cheeper, Unless you need a new canopy w/light, they can get quite pricey. My 55 gal's canopy broke and a new one is $200 cnd!! It could be. When you get a kit you sometimes find that you have to upgrade things like the filter etc. If the canopy is included on the thrift deal make sure it works. The canopy can be expensive and hard to replace. Price things separately then check the deals. i have had some great luck finding tanks at thrift stores especially sally anne. and most times they come with everything included and the last time i bought from them i got a 40g tank with all accesories for 15$. go for it!! i have had to recaulk the inside of tanks in most cases That's a great deal, just make sure it is good quality and doesn't have any weak spots. I got my tank from my boyfriend and it was cheaper than buying a whole starter set. That week petsmart was having an aquarium sale and so I got my filter and all that for very cheap. If you are starting your first aquraium get a pet perks club from petsmart and it will svae you $.
