Elongated Corralites Strawberry Shortcake

[mavena]

Hi all

What causes elongated vertical corralites in Strawberry Shirtcakes despite high light, strong random flow, good water parameters in ICP and low nutrients?

Corralites are often elongated in the mittle if this plating corral but normal on the sides

Thanks
Marco
