What is going on with this Stylocoeniella?

[kdx7214]

A while back I got two Stylocoeniella from Tidal Gardens. Both looked pretty good on arrival, but the green one had an edge that just didn't look right. Both corals were acclimated, dipped, and put in tank. The green one is dying, I'm just not sure what from. For quite some time it's been losing polyps, and overnight some large bites were taken out of the lost polyp area. The orange one is also now showing some receding tissue in very small spots on one side. I've attached some pics, although they are fairly blurry (cell phone camera and I suck at photography).

Any idea what the heck is going on here?

I don’t personnaly have any stylocoeniella but I know they are a very low light coral. How much light are you giving them?

Water parameters?

Assure moderate light amd moderate to medium flow and that calcium, salinity and Alk are not elevated.
Also inspect closely for any little bugs

I'll go run the Hannah checkers right now and see what's going on. Would dipping them again hurt anything? I can get the green one off the rock easily enough, but the orange one has already encrusted on one side, so it might be problematic.

if you dip - try iodine or Peroxide

Wouldn't peroxide kill everything? I do have some CoralRX I could use too. I just finished water tests and the alk was really low (6.2dkH) and the calcium was also low (300ppm) so I'm working on getting those fixed slowly.

As suspected- alk and CA which makes sense
Peroxide safe but skip it as those are your likely culprits

Mine is definitely a canary, for off parameters…their sensitive lol
Don’t dip, but get ur numbers right…
Mine also practically lives in the shade and seems to stay there, what’s the par you’res in?

No clue. I don't have access to a par meter. It's in the front under 6 T5 bulbs though it is at the very bottom.
