What is this on my acro?

[paintballer768]

I used reef chili for the first time last night also making my first time feeding my sps. This morning my blue mini colony had a white dot on the tip of the branch, where the polyp usually is. I went home at lunch and now there's a white stringy thing coming from the polyp.

Note : this is a few minutes after dropping some mysis in.

I think its a feeder tentacle, but I'm not sure, I've never seen it do that before. Ideas?

I should have been more specific. It's on the blue colony towards the middle of the photo. You can see the white filament I'm referring to contrasting on the birdsnest colony.

Mesenterial filament. Extrusion of the internal digestive structure. Not a big deal.

Could feeding cause a coral to do this? I fed again just now and 3 different polyps were doing this

Do you rinse mysis ? If not, phosphate will make sps do this. Coral will lost color if this happen often long term.

Yes, it is a feeding response.

Rinse mysis? I thaw out a portion of a cube. That is sufficient right?

You don't have to rinse mysis shrimp cubes...try an experiment. Make a gallon of fresh saltwater and measure your phosphates. Then toss a cube of frozen food in there, let it thaw then measure the phosphates again. Divide this number by the total volume of your tank an you'll see that it is basically negligible. If you run gfo, a skimmer, or do regular water changes it doesn't make a difference.
