Why are my Purple Death So Small?

[Koletang]

I got a single polyp a few months ago. It was very tiny and grew double the size. It also added two more polyps for a grand total of three. My question is, why are mine so small? They are about the size of my tiny zoas. I was at SWE and their purple death was way bigger.

What's that all about?

probably were babies when you got them.
