New Sea Creatures : Blue Dragon Sea Slug, and Jellyfish

Glaucus atlanticus or the Blue Dragon is a small, beautiful vibrant blue sea slug. I really want this in the game with the ability to carry around in a bucket. I believe it would be an interesting little creature to have in a pond or to see in a fish tank, and it wouldn't be hard to design. They should be breed able and have eggs like sea turtles. One problem is that the blue dragon isn't a plant eater, it eats things that are venomous like the Portuguese man o’ war. That would just mean Minecraft has to add jellyfish in game which should have been added long ago, in my opinion. I hope some people consider this.
