def a sea spider…
don’t think it’s a zoa eating spider specifically as they’re much smaller and generally white.
but i’d still get it out of the system and keep an eye out for more

yeah aquasd has gone way down hill,
they’ve always been a chop shop,
so i’m not surprised pests are getting through….
but this is probably the 3rd or 4th thread i’ve read in the past year mentioning spiders from aquasd.
no thanks, i’ll spend my money elsewhere!

That's worse than a zoa spider, looks like a stony coral eating spider. Had an outbreak of those last year, they eat EVERYTHING... I think interceptor will kill them the fastest though it is risky, they can reproduce in captivity and are nocturnal. I'd go around your tank when the lights turn off to see if you can spot them. Have any of your corals been showing signs of recession/stress lately? They often target only the edges of colonies and signs of them are an excess of mesentrinal filaments, recession, PE rapidly declining at night and a lessened feeding response. They often carry 2-3 eggs at a time. In my tank at least they were eating everything from cyphastrea to acanthophyllia. Probably killed about 100 in a 6 month period. Sorry you found these, good luck getting rid of them though! Hope this info helps because I lost way too much sleep trying to eradicate mine (I only did manual removal)

I have been dosing tanks and QT systems with milbemycin oximine for a very long time over my career and hobby, and in many cases using double and even sometimes triple the dose needed to be effective esp for indo acro white bugs that originally recommended by Dustin Dorton (23mg/ 380gal) ofor treating tegastes sp.
If using interceptor with only milbemycin oximine, I argue the opposite - the treatment is very low risk. It will generally not harm corals, just arthropods like pods, crabs and shrimp
Also, alone it's not 100% effective at treating all the members of pycnogonida, for 100% efficiency of elimination of pycnogonids, lufenuron is needed, it inhibits their molting process as its mechanism of action, so Sentinal ( milbemycin oximine+ lufenuron ) is right Rx to use, whether it's zoa eating or SPS eating spiders.
Just my two pennies and experience

Yea, should have cleared up that i meant risky for other arthropods/inverts and not so much corals/fish, I've never used interceptor to remove these but I've heard that it works so yea, though you definitely know more about this than me, thanks!

Thanks for the reply's.
Well this sucks the tank is only been up since August, its 15 gallon IM ( i drilled it and added a sump). I did start with live sand from golf live rocks another possible source of the spiders. I did add a few acros probably to early as i'm seeing one start to STN form the bottom up
Parameters from today
I’ll post a tank shot once the lights come on

Hey Everyone,
So i checked my tank with a flashlight this morning and found about 6 spiders on a acro frag, i would call it an infestation at this point. I think now i'm just going to reboot the tank this time without the live sand and frags from aqua SD.
If i pull the rock and soak it in bleach that would kill them right? or just go with new rock also

Bleach will kill off everything on those rocks, both good and bad

Yeah, not surprising knowing these spiders. Also i know they can survive both iodine and revive dips, probably came from the live rock since mine came from wild aussie corals. You could dose the tank with the interceptor that i and @C. Eymann mentioned, that will sterilize your tank from the sea spiders at least. If you're buying wild corals (like me) than I'd recommend covering any rock or skeleton with glue/putty to prevent them from getting into your system. Good luck my friend!
Ya they should be in everyone's black list IMO. They tried keeping $100 of mine and forcing a store credit on me for a clam they failed to ship. I got the $100 but had to threaten a dispute to get it. One of the clams they did ship arrived gaping and died in two days. It also had an aiptasia attached. That alone wasn't a big deal but any reputable vendor would have at least scraped it off before shipping.

Why not just try and source some Sentinal?
pycnogonida is a huge diverse class, and it seems not much is known about them.
I have seen several types, in addition to zoa eating spiders, SPS eating spiders, I have encountered spiders that I believe were actually predating on Montipora eating nudis or at least their eggs in an intake tank we were isolating some infected corals from a tank breakdown in, had 10 chunks of a big Montipora foliosa colony that had a bad nudi problem, each one had numerous nudi adults / egg bundles- except 3 colonies were nudi/egg free and when I looked closer each of those 3 colonies was teeming with very small spindly semi transparent sea spiders, but only found a handful on one of the 7 colonies with nudis, eventually it was decided that trying to get the colonies nudi free and ready for QT wasn't worth the time and risk and I forgot to save a few of the spiders.
There is another pycnogonid we might try culturing that exclusively eats another common reef pest, but I can't say too much about that.
Agreed, pycnogonids are incredibly resilient to dips and treatments, I was really surprised I was unable to kill zoa eating spiders with Interceptor when I first encountered them considering interceptor should be lethal to any crustacean/ arthropods, even at a 5X the recommended dosage. I only found success by using Sentinal/ M.O + lufenuron with zoa eating spiders. I haven't tried interceptor (Milbemycin Oximine) only for trying to eliminate the SPS eating type, could be worth a shop.
