[kenshin]

hi all,

this is my first time here, i'm impressed by all the info on these forums. thats why i joined up here. this forum ownz.
i'm from netherlands btw.

here's a question.
i want to add another species of lizzard (gecko or else) to my terra.

currently there is just one striped cape gecko (lygodactylus picturatus) in it my terra

also if i decide to put another striped cape in, do the male's kill each other? (how can i see what gender it is?)


what do you people suggest ?
