What's the best cheap gecko for a beginner with a 20-gallon tank?

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.

Yes, house geckos make good beginner reptile pets. You may not be able to interact/handle them like you could with crested or leopard geckos but they are easy to keep. her is a link to a care sheet: http://geckocare.net/house-gecko-care-sheet/

An adult crested gecko should be housed in a 20-gallon tank with screen top. Larger tanks will allow for better displays. In areas with moderate to high relative humidity, crested geckos will fare well in screen cages.

Hi there! We have a Crested Gecko and have so much fun with him! Don’t worry, they are a great starter reptile and are pretty easy to keep. In the winter we use a red light to keep the tank warmer, but not a specific heat lamp. This keeps the tank warm enough without getting too hot. Also very important is the humidity of the tank. Keeping it spritzed several times a day is necessary. We started with a tank your size and it probably would have been just fine long term, but we ended up purchasing a larger tank because we wanted a different look. Best of luck and have fun with your crestie! Thank you for using Pet Coach.

Yes, crested geckos are an excellent choice if you have never kept reptiles. An enclosure is easy to set up and the proper diet is easy to purchase. Follow the link for a caresheet. http://www.reptilesmagazine.com/Care-Sheets/Lizards/Crested-Gecko/

Thanks for reaching out about Blep. Using a aquarium as a terrarium should work well. Hamsters don't have anything that could be transmitted to a gecko, just clean out well. For geckos, husbandry is paramount, providing the correct temperature zone, UVB radiation exposure, humidity and diet will provide the best results. Good luck.

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.
