Bali Slimer issue

[Umair]

Dear Reefers,

I'm fairly new to sps world so please be kind and patient

Attached bali slimer frag i added some 5-6 months before and although has not shown great growth but PE have always been nice. One new branch started growing recently also. Meanwhile about 2 months before added some more frags which included a large size bali slimer frag or maybe colony as it had about 8-9 branches. All frags and the attached frag i got from the same local reefer.

Since last one week i have noticed both of my bali slimers had good polyp extension on the front but on the back all polyps were closed. Parameters have been ok in my opinion nitrates always at 10 ppm, PO4 ranging between 0.02-0.06, ALK 7.5-8.0, CAL 425-440, MG remains between 1380-1420. Only change i can think of is i put redsea top net cover about one week ago.

So can anyone see any pests in the photo or the frag simply seems disturbed?

TIA

Could be AEFW.
I think the bottom is its egg.
And on the white part of the acropora you can hardly see is aefw .

Those things to the left of the base look like vermetid snails, (snot snails) their mucus net can be irritating to coral and could be contributing to the issue here. I dont see any AEFW ? but adults are near impossible to see against flesh only a dip will knock them off to be able to confirm they are there, but the tissue recession doesn't match up with bite marks IMO, my money is on its due to those vermetid snails.

just my .02

Yes, you have vermetid snails. Their webs are irritating your slimer on that side. You need to remove the snails or cut and re-glue the slimer to a new plug.

Please dip it and figure out if it is really what I guess.

thank you will remove the plug, however the other large frag of bali slimer doesnt have any vermetid snails but still same issue.

should i dip in revive?

 

[Neoalchemist]

Might just be low light/ led shading. If you dip and don't see anything. You might need to add some supplemental lighting

I always dip in Coral RX with three times concentration for 3 minutes.

 

[Umair]

ok i just gave the dip for about three minutes in revive but i cannot see anything suspicious.

i've tired searching for aefw pics after dip but couldn't find, anyone here can share some pics so i can compare with mine.

I would agree it doesn’t look like aefw but the start of their damage can be very tricky to see on healthy coral. But I agree it’s the webs irritating the base. I would just superglue the area where they are. Especially if you didn’t see anything in the bucket. The worms curl up and wiggle when they fall off the coral in a dip and sometimes lay flat on the bottom. Adults are easy to spot but the babies you have to really look for.

the small frag seems better after dip and being mounted on a new plate. i think my issue is low light. Adding another fixture this week so will update if any improvement

 

[Umair]

just wanted to update, it seemed my lighting was not sufficient. since installing my new light fixture and playing around with my settings both frags are improving.

only bad thing is, after this post you guys pointed out my vermetid snails problem and now I realise they are all over my rocks

manually removed near the frags but they may just grow back and now it seems a constant battle.

I have them too. I don’t think there’s a lot we can do to be honest. I try to pull them off with pliers and glue them shut whenever they are bothering a coral. I might try a laser someday but that seems extreme. But fun

yeah spent some good two hours on Sunday morning crushing them with bone cutters.

btw is laser an option? would be easy and quick I guess

Beats having AEFW like I do

Don't think a laser would do anything to them. I have them in my system. I just cut them off when I see them.

I have seen a couple threads here about lasers. I haven’t tried.

I got tired of trying to remove the snails, so if I see one that may be irritating a frag I put some epoxy over it. Coraline algae covers the epoxy, so you never know its there.
