Used Fish Tanks for Sale

Used fish tanks can be a great way to get into fish owning on a budget. There is some important information you will want to get about the used tank before deciding to purchase.

Has the tank been repaired? If so, was the repair done by someone knowledgeable? Chips and cracks in a fish tank could lead to bigger problems, so be sure that these are either very minor or repaired before you take the tank home. At home, you can sand down any small imperfections.

The glue holding together a used fish tank can become worn and cause leaks. Old glue is generally not a big problem, and can be resealed. Just purchase some glue specially made for fish tanks, seal up any loose areas, and be sure to let the glue dry completely before adding water and fish. You don't want to spend the time and money on resealing and spring a leak because of a simple matter of not allowing the glue to dry!

Avoid used custom fish tanks. These have generally been made to fit a specific base, and will probably not fit a commercially available base. If you find a used tank that was custom made for a great price, ask for exact dimensions so you can compare it to your base.

Buying a used fish tank can be a budget-friendly way to start owning fish.
