The tag implication #40276 ichthyocentaur -> greek_mythology has been approved.

Reason: The ichthyocentaur is from Greek mythology, even depicted in Classic Greek art.

EDIT: The tag implication ichthyocentaur -> greek_mythology (forum #313761) has been approved by @bitWolfy.

Hmm. Normal centaur does not implicate greek_mythology.

create implication centaur (3887) -> greek_mythology (21244)

Reason: Centaurs as we know them originated in Greek mythology. This addresses the tagging discrepancy bitWolfy noted above.

Ichthyocentaurs are basically the standard horsy hippocentaur with the equine part's hindquarters replaced with the tail of a fish or dolphin. Other types of mythological centaurs include the donkey-bottomed onocentaurs and the cow-bottomed bucentaurs.

Analysis:
pegasus does not imply greek_mythology, presumably because if it did, greek_mythology would become 90% mlp, and be useless for searching.

ichthyocentaur has 7 images, 6 of which already have greek_mythology. So that alias is harmless.

greek_mythology has 10k images. The most common tag implicating greek_mythology is minotaur, at 3.4k, followed by harpy at 1.7k and phoenix at 1.5k. centaur has 2k, between minotaur and harpy, of which only a few have greek_mythology already. So centaurs would occupy 20% of the tag's search space. I'm inclined to say anything less than 30% would be acceptable.
