I'm pretty new to this game. I'm around level 30ish and so has be*** the terror of constant Fruitfuls and firestorms. (I remember when I first started my sadness that i would probably never be able to breed a Fruitful.... was I wrong or what as they seem to be stalking to me!)

Anyway, I'm writing this post to ask your experience of what you think best to do with these critters that are taking up space in my Habitats.

Do I leave them there to assist with gaining money?
Do I sell them?
Do I trade them for gems? (This is what I have been doing, but find it wastes my food a valuable evolving time i could put into other dragons...)

Just wanted to know what other people do and your opinions? What you think works best? Should I be trading at a later date and just selling for now? Is there another option I'm missing.

Would love all your help, thoughts and advice!
