The centers look solid, more like Purple People Eaters than Purple Monsters. The problem is that People Eaters have a green mouth and it looks like these don't.
Ok I took a photo with a white light and they have a slightly orange center. Now that I remember I bought some corals with green polyps and orange mouth some time ago but they changed the colour in years maybe?
@ShanePike the OP is in Europe, they don't have the same supply chain as we do here in the US meaning that while we often get stuff they don't they also get stuff that we don't. Prime example is Mind tricks, I had to look at them in European collections for years before they finally made it to the US.
In this case this guy doesn't neatly align with any thing named or even a bucket strain (group of zoas with similar characteristics). Closest thing would be what occasionally sells as 'mindbenders' but the color seems a bit washed out.
