it accually depends on the size of the Gecko, they ill need a fairly large tank, and if you have more than one gecko in the same tank i recomend to get a very large tank. from mystery person
A fullgrown medium - large species of gecko require 10 Gallons per adult. 12x12x12 is a 10 gallon tank.
gkos need a heat lamp water food worms of crickets and a cage an some big rocks
The cage being to damp or being to unclean. You should check their is nothing rotting and no poo's that you havn't cleaned up.
sure but they should be the same sex unless you want more tortoises
Really depends on how big the bird is / how big it will get. The bigger the bird, the bigger the cage you will need. I would recommend getting at least a 20Lx20Wx29H sized cage for a parrot.
In a big cage
you shouldn't cage dolphins dolphins need relaxing environments, also if you picked out a normal cage like a dog cage it (obviously) wouldn't keep water in
The insets should not be bigger than the space between your geckos eyes.
No - they will fight for dominance, resulting in stress for the 'weaker' of the two.

If i were you i would get a big cage so the guinea pig can run around Good luck with your piggie I have a big cage that holds 2 guinea pigs and they chase each other around the whole cage!!!
That is normal. Just sweep it out of the cage, and that means your gecko is healthy. For more information on geckos, go to www.wikipedia.org and type in geckos.
