Is this bad? ID ¿pest? eggs

[IronVulture]

Just got home from a 3 day trip and noticed this on one of my acros can anyone id it.

What is your no3 and po4

 

[IronVulture]

No3 8
Po4 .08
Alk 7.3

All red sea tested just now

I'm pretty surprised to see that on the sand. Usually you can't get enough flow to the skin of the animal to let it breath correctly much less absorb alk. The sand usually gets blown away by that much flow.

Yea it's not on the sand

Had to use the flash my lights have already gone all blue

Dip it! Looks like they might be AEFW eggs. Better to dip it since it isn't mounted to any rock work.

 

[IronVulture]

If it is eggs the dip won't kill them but I can scrape them off and or cut it off this disk and re glue it to another

 

[IronVulture]

I don't think they are afew eggs though

Hi mate, i think it might be a water issue since the tissue on the tip pointing right at us down low is also missing. Many things lay eggs at the site of STN whilst feeding on dying tissue etc so those little eggs if they are that are likely to have nothing to do with the problem. I have seen the same thing happen with my own acros over the years. Have you double checked all parameters to make sure nothing went askew while you were gone.
Just trying to give some ideas of where to start looking, do you calibrate your refractometer with solution because that base tissue loss reminds me of what i saw when my salinity went out of whack big time.

Salinity is at 1.024 tested with Milwaukee seawater refractometer

I did dip the coral in me coral dip and I came up with two flat worms

I picked the only other coral from my tank that looked slightly stressed and dipped it as well but didn't find anything but copepods.

Hopefully I caught it before it becomes a problem. I will continue to monitor all corals for signs of flat worms. I'm still pretty sure the little "egg like" balls from my original post were not aefw eggs

For a little back story on this piece I got it from a guy that took it out of his personal display after a crash caused by af salt according to him. It has been in my tank since last Wednesday on the bottom of my tank away from all other acros. I have a lot of flow in the tank so I don't know how well the worms can move about.

I'm glad you dipped that acro and found the worms mate, hopefully they didn't get a chance to spread. Signs of pests and tissue thinning/loss are much easier to spot at night under torch light due to the high contrast so perhaps carry out a weekly survey for the next month just in case. If you ever see shiny little crab eyes glowing in one of your acros at night it's a bad hairy crab - commensal's never reflect torchlight.

I'll be checking on a nightly basis for pest. Do you have any idea about the purplish blue egg looking things?

Anyone know what these could be?
