Frogspown dying?

[chevyman1856]

It use to be a lot larger? Now it shrinking?

Any ideas

What kind of light and flow? They like moderate flow and bright light

haven't change were it was for over a year, very bright leds and 2mp10

tank is a 40 breeder

I don't see any white skeleton in the photo. It just looks like the polyps are not fully extended. This coral usually does not need to be target fed, but it might be worthwhile to give that a try and see if it responds.

If it doesn't extend fully you might want to evaluate your parameters, temperature, salinity, flow, light & placement...all the usual stuff. Is something picking on it? I don't hear much about that or parasites with this coral but that may be a possibility.

Looks like the flow isn't too much (hard to say from a pic, but the extended tentacles seem to be able to stretch where they want). If lights haven't changed it is highly unlikely that is it.

Temp, pH, salintiy and alk are what I would look at. Specifically for swings in parameters or for extremes. Temp and pH have a tendency to get ignored in the hobby and can have significant effects if they start to go out of control. High alk will also do significant damage to LPS. If you do have a pH issue I wouldn't immediately start buffering but instead figure out what might be causing it (low alk, low mag, high CO2, might need hydroxide to balance carbonate/ bicarbonate ratio). In a 40 breeder water parameters can swing quickly as your water volume is likely only 20 gallons.

Thanks there is a 20g sump too going to check all parameters.

PH is stable at 8 8.3.
Temp 77-78
Alk 7.6
Cal 420

Check your magnesium too. IME, Euphyllia can get grumpy if mag gets too low.

 

[chevyman1856]

Mg.checked 1160

 

[chevyman1856]

Started dosing to get that up

agreed, I like to keep system at 1350-1400. slowly tho!!!
