Umbrella effect in coral growth

[fruitymint]

got some blue zoas that i've had for a bit now... they've always been happy in their spot, but out of nowhere they started doing this weird inside out thing or umbrella effect... nothing's changed with the lighting or flow, and they're still in the same spot... they actually seemed to love it there... been like this for a month now and they're not melting or dying or anything, actually seeing some new growth... anyone got any ideas what's going on with them?

I'm not sure what's going on with your zoas, never heard of them turning inside out like that. Can you post a pic of what's happening, would love to see it and maybe we can figure out what's going on.

I'm stumped, never seen this before - my blue zoas just flipped out, literally, like inside out or umbrella style, no changes to lighting or flow, same spot forever. They were thriving, loved that spot, been like this a month now, no signs of melting or dying, actually lots of new growth. Any ideas what's going on?

I've read that it could be too much light, but I've had a colony of magicians do this on and off, even after being in the same spot for almost two years - they just kinda "reach" for light sometimes. Zoas are weird, I guess. Keep an eye on them and if this umbrella look doesn't change and the colony starts to dwindle, maybe think about moving them a bit then.

They'll likely need more flow than you'd expect, zoas can be weird but they do seem to thrive with a bit more water movement, just something to consider.
