Hi Denny,
Fish can be construed to mean singular AND plural.
ie, "A school of fish." or "I purchased an aquarium full of GoldFish!"
from webster.com:
"Main Entry: fish
Pronunciation: fish
Function: noun
Inflected Form(s): plural fish or fish·es
"
So the exact term "Fish" has BOTH singular and plural searches all in one,
and this domain is unique and special, not to mention very valuable.
