Dreamlike underwater city of glowing coral and crystal domes

A fantastical underwater city built within colossal, bioluminescent coral formations. Strange, aquatic beings with jewel-like eyes swim through crystalline domes, tending to glowing flora. The scene is dreamlike and otherworldly, with soft, ambient light filtering through the water. Imagine the architectural style of Zaha Hadid merged with the organic forms of Ernst Haeckel, rendered in a vibrant, glowing watercolor with a hint of dark fantasy.
