I was doing research again today on my two Guppies that have/had heart shaped tails and today out of the blue I find a Medusa Guppy listed under possible tail patterns. When looking at the Google images though, there were only some that had an indent in their tails. And many of the Medusa Guppies I pulled up were a combo of different types. I couldn't find an answer to my question...so I ask here. Guppy Gurus....what makes a Guppy a Medusa? Thanks in advance!
