I think Purple Hornets are over-rated...the polyps are so small...like Pufferpunk says, you can only enjoy them with a magnifying glass. Maybe when the get to be a big colony, they be impressive.
Now I got these at at swap for $10 as just plain brown polyps, but I like them cause they were so large..a month later they look like this...
I've had these yellows a month and they just keep getting better
I pick up this colony totally browned out but the polyps are large most over 1/2" and it's a PE of some type and the color is changing everyday, they are getting a bluish ring, the skirts are still up in the air, but the mouths have turned PE green
