Coral dying

[Horn]

2 days ago I saw some tenticles falling off my frogspawn. Now we heads have no tenticles. I think my other Corals look good but I don't know.

What happened to my frogspawn? Will is spread? My tank looks like crap with the heads and no tenticles. Will the tenticles grow back? Should I break the heads off?

I get a good zoom shot at the end of the video.

Video is still processing. It should be done in a min.

I still can't view the video........

Maybe I don't get what coral you were trying to show.... I didn't see what you were describing. I saw a frogspawn that looked like it wasn't fully expanded, but that's it...

If you pause the video between the 2 and 4 second mark you can see two heads with no tenticles. It is the bottom middle of the colony.

Can you take a picture or maybe a video where you aren't jumping around?

I see at the very end the two heads you are referring to. I do not see any signs of brown jelly, so that is good. Sometimes heads get blocked of nutrients and die. Looks like the others are a bit off color (whitish), but could be the video or my monitor. Could something have eaten them or stung them? Keep and eye on the rest. If more start to perish, pull it out and really do a good dip and check for parasites.

Anything new to tank? Nitrates too low? Are you feeding them? Lights still good?
