The size of the enclosure depends on the number of geckos to be housed in it. Keep in mind that although females generally get along, no more than one male can be kept in each enclosure. A single gecko can be housed in a 10 gallon size aquarium. Three to five geckos can be kept in a 20-30 gallon aquarium. There is a lot of debate over which substrate should be used with these geckos. We've used a variety including sand, calci-sand, cypress mulch, cage carpet, newspaper, paper towel, and others.
The most closely known relative of the GalÃ¡pagos finches is T. obscura. They were first collected by Charles Darwin on the GalÃ¡pagos Islands during the second voyage of the Beagle. Apart from the Cocos finch, which is from Cocos Island, the others are found only on the GalÃ¡pagos Islands. The term Darwin's finches was first applied by Percy Lowe in 1936, and popularised in 1947 by David Lack in his book Darwin's Finches.
Charles Darwin was a naturalist. His major contribution to science was the Theory of Evolution.
