Trading For Black Gems

[Jnny2good]

I tried to trade my Leos for black jems, but the trade icon is greyed out. Are Leo dragons not tradable? If so, why?

Nom they aren'r tradable, because Leo is the main dragon to get the rest of the zodiac dragons.
Tropic, Royal and Dino, are the same.

What level does the dragon (like a Magma) need to be to trade it and receive a Large Black gem? Level 4? Or does it need to be higher? Thanks!

Every dragon that can be trade, needs to be in the minimum at level 4.
