a glass apology to the ocean, where you play god over creatures unimpressed by your effort

means A transparent container, usually glass or acrylic and filled with water, in which fish and other aquatic creatures are kept alive for observation or pleasure.

from Both halves are plain old English doing exactly what they say. "Fish" goes back to Old English fisc, with cousins all across the Germanic family (German Fisch, and ultimately a relative of Latin piscis). "Tank" is the surprising one: it likely came into English in the early 1600s from India, where Portuguese tanque and local words for a reservoir or cistern (Gujarati tankh, possibly tracing back to Sanskrit) met and merged. So a "fish tank" is, etymologically, fish kept in a borrowed Indian reservoir — the watery sense of "tank" long predating the armored vehicle, which was named after it as wartime code.
