I have an old 5 gal tank and I did some research. I found pictus geckos and found out they can fit in a 5 gal but that is all I know. What is the bare-minimum size tank they need to live in. What else will I need substrate,food, stuff like that.

I've talked to many people, visited websites and viewed many caresheets and have not found one that recommends anything under 10 gallons. In all reality, they are small geckos but they need room to move, and you can't get a heat gradient in a 5 gallon. That is really just too small for anything.

Pictus geckos are terrestrial and require a minimum of 10-20 gal. The smaller madagascan geckos, p. androyenisis can fit in a 5-10 gal.

As for substrate I find juveniles/adults do best on coco-fiber/bed-a-beast for natural breaking down purposes and humidity. I put all my hatchlings on paper towels until they are at least 4 months old. They can be rather clumsy eaters.

Humidity should be 50-80%

They are insectivores and like a variety. Adults will eat 3/8" size crickets. They will also enjoy mealworms in a dish. Just make sure everything is appropriately sized.

The preferred temperature for pictus is 77-88F. Make sure you don't over heat and temperatures should never go below 65. They are nocturnal so no uvb lighting is necessary.

Another thing with pictus is they are extremely prolific and females often die young because of over breeding, so if you ever decide to get two be sure to have them separated. They breed all year round so as long as they are together they will keep breeding. Never house two males together.

Pictus geckos usually don't like to be held, they can be tamed, but definitely can surprise you. One day you think they are calm and tame then all of a sudden they jump out of your hands and you're chasing them all of the floor. They are extremely fast. So if you are wanting a gecko to observe awesome hunting skills, these are those. But if you are wanting a gecko to handle they might not be the best choice. I usually only handle mine for health checks and cage cleaning.

I think I covered everything... if you have anymore questions just ask.
