Zoa issue??

[willclark7]

My two Zoa corals over the last 3 months have slowly evaporated any advice on why that could be? I have also been what looks like some sort of bridge forming between the two, I have attached a photo?

All parameters are fine as are all the other corals

What lives in the tank? Both fish and inverts. Maybe something is eating them

all parameters fine is not helpful unfortunately. Just post them so we can get a better idea of the tanks environment

I have 2 clowns, 1 tomini tang, 1 blenny, 1 fire shrimp, 1 Randall shrimp, 2 urchins and 4 snails.

Do you know what the sand looking bridge is?

Looks like the Randall shrimp dug a tunnel

The zoas could be getting plowed through by the urchins.
