Well, you don't need to keep them in order to get shrine credit, but if you want to go to level 20 with them, then yes, they waste a lot of food (nearly 400K) to sell a level fifteen if you want to then taken them higher.

I think you should just keep the dragons you want to get to twenty, then sell the excess (any that you do not want to display in your habitats). You can get seven shrines to gold with only Panlong and Bloom, which means you would not need to sell any of them, but that doesn't solve the problem for metal. The only value I can see in keeping them beyond that might be for future updates to the game that allow leveling them higher thant 20 (such as Platinum shrines)

Personally, I'll be happy just to get a single dragon to level twenty. That, by itself, seems like unobtanium.
