The Crested Gecko (or Correlophus Ciliatus) is essentially 70% frugivorous but also feeds on flower nectars and insects. The Gecko will eat very ripe fruit. To know which fruit is good to give to your animal, you have to look at the calcium level in relation to its phosphorus level (Ca:P) (2 :1). You should favor fruits that provide more calcium.
Here is what it can eat in terms of fruit (kernel excluded):
A
Apples
Apricots
B
Blackberries
Blackcurrants
Blueberries
C
Cherries
F
Fresh figs
G
Grapes
H
Honeydew melon
K
Kiwi
M
Mango
P
Papaya
Persimmon
Pineapple
R
Raspberries
S
Strawberries
W
Watermelon
You can nevertheless also give occasionally and by mixing with the other fruits of the above list: bananas, pears, guava, peaches, plums. They are not toxic fruits for your Crested Gecko but they have a much too low calcium to phosphorus content. To balance it out you can mix fresh figs and papaya with bananas and apricots for example.
Be careful, avoid citrus fruits that contain citric acid such as oranges.
Never give rhubarb, carambola or avocado as they are dangerously toxic to your reptiles.
