I caught the grey blue tokay as attached photos last month. And the darker last night. I supposed 1of them is male and another is female because the different of its colour. Can someone tell me which 1 is male n which is female? The new comer (darker tokay) was bitten by the blue grey tokay which I got it earlier in the tank. But now seems to be okay. Shall I separate them? They are both aggressive which I hardly find a right method to separate them. My intention is trying to get a cage mate for it or/and to breed. The greyish blue is slightly bigger than the darker one. But greyish doesnt bark at all. As I read from some articles that my tokay is the normal tokay am I right? Hope someone is kind enough to advice me. I have attached photos. Any suggestion about the settings of the tank, please advice, p/s the pet shop in my area (Hatyai, Thailand) only sells birds, hamster, cats and dogs. So, hope the settings source which I can diy or find from jungle.
