What is the main conflict in The Fish by Marianne Moore?

Marianne Moore wrote "The Fish" in 1918 but it was published later in her first collection, Poems, in 1921. This collection was published, without her knowledge, in England by two of Moore's friends. An example of rhymed syllabic verse, "The Fish" highlights Moore's ability for precise visual description. Ironically, the poem is not about fish at all, but rather the relationship among a seaside cliff, sea life, and the sea itself. Sunlight acts upon the sea and its creatures, and the sea acts upon a cliff.
