My pulsing xenia was very happy until my yellow goby died. Now it is silvery white (it used to be clearly pink) and the stalks and arms seem dry, brittle and withered. It still pulses and responds to light. but it is very different.
My yellow goby died last weekend. Before the death, he perched and played in the Xenia quite a bit. It seemed very much like a clown and an anemone... Now the goby is gone and the xenia seems to be in mourning! Do you think it is possible the coral misses the fish?
I have tested the water every day and found no problems. No ammonia, nitrites, or nitrates. pH was 8.6 and alkaline normal. 2 days ago, I did a 20% wc
in order to fight some cyno. Today, chemistry is still good except for nitrite (reading .25) I did another 20% wc
but I am wondering if pH can be too high.
My pH is steady at the top of my test chart which goes to 8.6. Everyone else seems to have lower pH.. Would high pH hurt my fish or coral?
BTW. the tank is new (8 or 10 weeks) and the goby was the first to die.
Thanks for any ideas!
