What are these "tendons" on my Frogspawn?

[Webmanny]

Hey guys,

I occasionally notice these lighter looking "tendons" areas on the branches of my Frogspawns. Hammers don't do this, just my Frogspawns. Have you guys seen this before and what does it mean?

My tank is a 36 bowfront. Has been up and running for about 2 years. I have a bunch of LPS corals and some soft corals too.

Light is a T5/LED hybrid light. All parameters look fine and nothing has really changed recently. These corals have done this before once, but went back to normal after a few weeks.

Mine does that when I turn off the flow for a water change. It then really stretches.

Thank you for your feedback.

That is weird. It has a normal amount of flow where it is. I don't think flow is the issue, but I may be wrong. Lets see if some other team members have other recommendations.

I have the same thing on my frogspawn, right where 2 tentacles were that were white is right where it split. Not sure of that means anything though as I have other white "tendons" as you call it, in other spots.

Mine looks the same, I think it's fine
