No matter if you are a new aquarium owner or an experienced expert, I always advise to think before you purchase an aquarium at a store like Pet Smart. Retail pet stores charge two or three times as much as places like Amazon, sellers on eBay and Craigslist, or yard sales.
The best place to buy a used aquarium is on Craigslist. There are many people who are wanting to sell them, but if you keep waiting, you will find a good deal. When you get to the seller’s house to see the aquarium, make sure it is in good condition, comes with working components, and has no cracks, leaks, or any other defects.
When I was looking to get a new aquarium in April, the first place I looked was eBay. There are many sellers that have 10 and 20 gallon aquariums listed, but finding a larger aquarium that is 20 gallons or more can be difficult. The problem with eBay is that unlike Craigslist, you can not see the tank in person unless you pick it up locally.
Another place I have found aquariums for low prices is at yard sales. The sellers who do not advertise their fish tank on Craigslist will most likely be selling it at a yard sale. Like Craigslist transactions, make sure the aquarium is in good condition with no cracks, leaks, or defects.
If you don’t feel like buying a used aquarium, you can always check out Amazon. Most of the products sold on Amazon are the cheapest on the Internet with free shipping. In the past, I have ordered two aquariums on Amazon – a 2 gallon tank for my betta and a 10 gallon tank for molly breeding. The 2 gallon tank is acrylic, but the 10 gallon tank is glass. Both arrived in good condition in a timely manor and both were less expensive than the same models at Pet Smart and other retail stores.
