Friends of the forum, I need some advice again.
In my predominantly softies aquarium I have 2 varieties of Xenia pumping, one brown and one pink.
The brown variety pulsates and grows quickly.
I have problems with the pink variety. It's the second time I've inserted it, it pulsates very well and grows (slowly) for a few months.
Then it begins to shorten the stems, shrinks the polyps and regresses without ever stopping pulsating.
The colony disappears completely within a few weeks.
Meanwhile the brown variety continues to grow undisturbed. No changes in light or flows.
Salinity 1.026, NO3 12, PO4 0.05, Kh 8, Ca 480, Mg 1500. I tried to dose iodine with no results, it also seems indifferent to the carbon in the sump, whether it is there or not, its life cycle is the same. Can there be bacterial or virus infections on xenia that cause it to regress? I haven't seen any macroscopic parasites...
