A fish tank will need a filter, a light/hood and a heater. Make sure the filter is rated for at least twice the tank volume. The heater should be adjustable since water temperature will depend on the species of fish. Good "starter" fish include Tetras, Mollies, Danios or Tetras. A new tank should be set up and left running empty for several weeks before adding fish. A pinch of flake food can be sprinkled in daily. This "cycling" will allow a population of beneficial bacteria to colonize the tank and filter. These bacteria will break down wastes (ammonia, nitrites and nitrates) which are toxic to fish.

A 10 gallon tank can be purchased in the local Petco for less than twenty dollars ( https://www.petco.com/shop/en/petcostore/product/fish/fish-aquariums-kits/aquariums-up-to-ten-gallons/aqueon-standard-glass-aquarium-tank-10-gallon ). It would be easier to keep and secure than a laundry hamper. Given the temps required for geckos, plastic may not be the best option either. You will need a a heat lamp for day use and maybe a heat source if nighttime temperatures drop below 70 F. You can use slate, reptile carpet, plain paper towels or a coconut fiber substrate.

The width will limit the tank size. The largest tank would be a 25 gallon tank. If you choose this size, make sure the stand can support upwards of 300lbs. That is what the tank will weigh once filled and set up.

As for what kind of tank you will need: Basically a square fish tank, do not get a bowl. You will likely need a heater and an air pump, and a thermometer, It is easiest to by a complete kit at a pet shop. As for size of tank: The bigger is always the better....however a minimum size will be determined by the type of fish and their average size they will grow into, So once we know what type of fish you have and how many, we can tell you how big your tank needs to be and what type of "furniture" (rocks, plants, gravel) you will need.

An adult slider should have at least 10 gallons of water per inch of shell length. Bigger is always better though, so if budget and space allow then try for a 75 or even 90 gallon tank. Provide a UVB light source unblocked by glass, plexiglass or fine mesh. Heat sources (for the water and for basking out of the water) are also necessary. A basking platform out of the water should be provided. Use a filter that is rated for at least twice the volume of any tank you choose. This will help maintain water quality. You can read more about keeping sliders at the links below. http://www.anapsid.org/reslider.html http://www.reptilesmagazine.com/Red-Eared-Slider-Care-Sheet/
