Frogspawn, too much flow?

[flakey]

I purchased a frogspawn a month ago and it has always expended very nicely, but I have just recently found damage to part of the flesh. The damage only seems to be in this one area and the only reason I can put on it is that this area is most exposed to flow.

This is a picture of my tank. I have circled the area that is damaged and probably slightly more exposed to higher flow. I have to say the flow is not intense and the frogspawn is swaying nicely.

This picture shows the damage

I have re-positioned the frogspawn so that the base is more shielded, but please let me know if it could be something else.

It could be flow, I have a hammer and torch and they seem to do better in low to moderate flow, just enough that the tentacles are wiggling. Also check and make sure that nothing is bothering it for as pest.

These are actually Octospawn or Grape Corals. They are the same family, but they are a bit more delicate than Frogspawn. I would move it to an area of a bit less flow and give it some time.

Please note that in my experience, they also require a bit less light. I have mine down on the sand and it is doing great. Just my two cents.

giving it another inspection now the lights are on and it looks a bit worse than I initially thought. The damage is all around the flesh and not just that small area. I've just moved it lower down to the sand bed and will see how things go.
the only pest I know of is flatworm but I don't think it would cause this type of damage.
Does anyone know the survival rate in the current state?

The only change I've made recently is to dose Red Sea Reef Energy. Anyone have any opinions on this stuff?

Octospawn yes, Grape no. Grape Coral is Euphyllia cristata and is not branchy like Octospawn, Euphyllia yaeyamaensis.

My frogspawn did the same thing. When I moved it to a lower flow area, after a couple of days, it bounced back nicely.

Correct. I could not see the branches from the picture and I was on the fence about which one it could have been, but you are correct. It does look more like a Octospawn.

Cool. I was just trying to differentiate between octospawn and grape. Hope I didn't offend. E. cristata is the one common Euphyllia (hammer, torch, frogspawn, octospawn, grape) I don't have. I may have to fix that. I like octospawn particularly as it seems to concentrate all the nubbly goodness of frogspawn in a tighter package. ☺

Well after moving it to a lower flow area, it looked far worse, mouth gaping open etc so flow was probably not the cause. I have now upped the flow so it's slightly higher than before

Maybe flow was too slow?

I also purchased a new test kit and found that all levels were fine but nitrate was 10. My previous kit told me 0. Not sure if this would cause the damage though.

 

[Reef Bass]

Nitrates at 10 did not do that.
