i was given these as purple hornets that lost their color and was told the color comes back but its been a little over a month and i still don't see any color coming back. Although, i have had 3 more polyps since iv got them but they all see to have the same color. these are my first hornets that's why i am a little confused.
are these purple hornets?
if yes, what can i do to get their color back?
