Recently I had added 2 peppermint shrimp to my 8 month old fluval flex 13.5 gal
. For about 2 weeks they kept walking in my corals and my corals would never open up. Yesturday I did a watwr change and added a bubble tip anemone to the tank at fist it attached to the rock and ingulfed itself. I carefully peeled it off and moved its spot but joe it wonít attach to a rock. Did I kill it by stressing it out to much? The corals still Havenít opened up and now I am wondering if thereís an issue with my water because my reef lobster as well as 2 snails died. Phosphate, Amonia are all good. Nitrate at 20 ppm
. Also the anemone has a slime like goo coming off.
