I was wondering where I can get a good and preferably cheap tank. Currently I have a 20 gallon tank but I would really like something bigger. Any advice?
Craigslist, yard sales and thrift stores have been good to me.
Know what you want and how much you are willing to pay beforehand.
I wont go over $1 per gallon for used aquariums and I try to find ones that include lamps lids and other accessories.
I always look for people selling cracked and/or leaky tanks. Fishkeepers consider them junk, but I don't need them to hold water. I put a little silicone over the cracks and they're good to go.
If you have a Petco in your area I think they are having a dollar per gallon sale going on right now. 40 gallon for 40 bucks, pretty good. Brand new with no cleaning up or fixing.
so far I have accumulated five of the 4 foot long (55 gallon?) aquariums for free.
Just keep your eyes open, People will put leaky fish tanks out front of the house with a sign that says "free" every once in a while.
I stopped buying aquariums ages ago, I never pass up a free one, not ever. as a result I have 4 down in the basement as backups... I still would not turn down one today.
I don't know where you are but Denver craigslist is a gold mine for used tanks (compared to Baltimore, where I used to live). This weekend someone was selling a 100gal with stand for $100. I grabbed a complete 30gal hex aquarium kit with real wood stand for $50.
