Montipora slowly dying again

[zheka757]

So this is 2 diferent pictures of my monti, one In my frag tank, one on my display, both using same water. Almost at same time they started doing this, closing up and looks like going to die, this coral being in my tank for about 6 months now, and I got it as a frag, and got another frag from it. I can't say it's lights, couse it's being fine up to this point and in both tanks under different lights.

This is my second set of Montis that is doing same thing after being fine for a long time. Other sps are doing great such as acropora

Some causes:

Stinging from nearby coral
high alk
low calcium
temp too warm
Low salinity
Insufficient or too much water flow - Moderate is good
High nitrates
high phosphate
Low nutrients in tank

No worries if the polyps were gone , just make sure it’s not bleaching and exposing the white skeleton.
