Frogspawn Spew

[BClute]

I've noticed my hammer doing this the other night, and now my frogspawn. If you look at the picture you can see a brown string of gunk being spewed out. From my understanding this is zooxanthellae, but what I don't understand is that I thought this only happens when the coral is not happy, under stress, or right before the coral bites the dust. From what I can tell both the hammer and frogspawn are both happy. Both are extended and not closed up. The frogspawn did recover from a fall s week and half ago, but it's pretty much 100 percent now. Should I be worried about this?

Nothing to worry about.

I've had my frogspawn do this occasionally, didn't seem to be an issue.
Fish usually eat it.

I thought this was also how they went to the bathroom? I was actually going to post a picture myself of a hammer doing this. I do spot feed mine mysis too mine retracts to do this and then once it's finished, fully extends again. Toilet break?

YEs they do. They will empty themselves this way. If you have them in a bag during shipping and they do that, they can get infected. In an aquarium with good flow, the waste will get washed away like in the wild and get into your filtration. Not an issue.

It's not going to the bathroom.

It is discharging zooxanthellae.

They can do this for a number of reasons.

Simply acclimating to brighter light can cause this. In extreme situations, strong lighting can lead to excessive zooxanthellae discharging and bleaching. The cure is to simply reduce lighting.

This can happen, on a regular basis, in a system with elevated nutrients, where zooxanthellae reproduce rapidly. The cure in this case is to simply clean up the system and reduce nutrients.

All corals containing zooxanthellae must regulate the population within them. Occasionally they may discharge a few. In a healthy, well established coral, we won't even notice this. When the coral is discharging zooxanthellae to the degree shown in the pic's above, it is an indication of a problem. Usually, it's a simple fix. Insure temperature is proper, insure lighting is suitable, and/or reduce the fertilizers that's causing an excessive reproduction of zooxanthellae.

Yeah I had read that it could zooxanthallae. I have a number of euphyllia though and all of my parameters are absolutely great. It only seems to be the one head that does it. So why would it do that when non of the others are? Confusing...

So why would it do that when non of the others are? When you say reduce fertiliser, wouldn't that again lead back to the discharge of waste? Sorry to seem like an imbecile, I'm still trying to learn as much as I can.
