A-quar-i-um or A-qua-ri-um?

When was the last time someone composed music and wrote a poem to you?
An aquarium (plural: aquariums or aquaria) is a vivarium of any size having at least one transparent side in which water-dwelling plants or animals are kept and displayed;  combiining the Latin root aqua, meaning water, with the suffix -arium, meaning "a place for relating to".

Music (below) is nice though.  I promise I'll stop reading encyclopedias someday.

Let’s change the mood in the merry vivarium, 
Let’s try for calm with a placid aquarium. 
Some fish are plain and some are exotic 
Watching them swim is deeply hypnotic. 
That’s why some dentists keep tanks in the offices 
So while they’re peering down our esophaguses 
We will have something serene to delight us, 
Rather than thoughts of the dread gingivitis. 
While they are wrestling recalcitrant plaque off, 
We are prevented from telling them, “Back off!” 
By the display of aquatic adventure, 
Buttressing us from the prospect of dentures. 
Strange are the fish and the motives that power them 
Guppies have babies, and then they devour them. 
Me, I would rather make do with a croissant, 
But one fellow’s meat is another man’s “poisson”.
