Lumicora

From BoardGameGeek:

In the oceans around the equator, a beautiful habitat shines with bright colors. Coral reefs are underwater ecosystems and home to many species. However, as a result of global warming, reefs have been declining massively in recent decades, and it is up to us to protect them to keep them alive! Lumicora is a three-dimensional tile-laying game that relies on clever planning and timing. Gather colorful coral tiles and construct a beautiful luminescent reef. -description from the publisher
