No matter what gecko you decide....Always get the biggest tank you can
Arboreal Species..As Much Height as possible...
Terrestrial... as much length and width possible. My Leopard Gecko has its own 48"w x 24"width x 12" Height with plenty of stuff to crawl and climb on
Unless you want dirty glass to see through go with some sort of Tank that has doors to open to clean once in awhile. I use to use only All Glass aquariums. I have since switched over to either ZooMed or ExoTerra Tank.
Both Has their advantages..
ZooMed...Cheaper but a Single door...view Is Better without a seam down the Middle...More Chance of a Critter Escaping..No Cheesy Background or accessories
ExoTerra...Double Door...More Expensive...Cheesy Background Included...( I never use for many Reasons)..Cheesy Artificial Plants and other stuff i never use..see below
I have a External Ultrasonic humidifier..so easy to adapt...Never use the Foggers that go inside a Tank..
If you just have to use Aquariums...Keep an Eye on Your Local Petcos...They have $1 per gallon Sales quite freguently..$40 for a 40 Gallon is much nicer than over $100
Get Digital Timer....A Variety is available...look around..You can find cheep good versions
I use Natural Organic soils, Plants, Rocks, and Wood in My Tanks..
I hand Mist My Tanks ... although I do own a MistKing Misting System..but have not set it up because I keep moving My tanks around.
I usually go with a No Background since I have No artistic Talent...after many many many attempts I gave up trying to Make My own Backgrounds..When I do use a Background I use Universal Rock Backgrounds...Fantastic product and the variety is growing daily
You Want something Naturally Colorful or Dull?
Something Small Medium or Large?
Most Geckos, except at breeding Time need to be kept separate...
10 Gallon possibilities for starter reptile( not just Geckos) is Green or Brown Anole..they stay small..several can be kept in a 10 Gallon Tank..Mourning Geckos..very Small and they reproduce without Males..
Do a Web search for Reptile Shows in your Area....
