I'm looking into purchasing a lettuce nudibranch to help moderate my GHA, but I can't find information about ich transmission and quarantine for them. I'm hoping they might not require it since they don't have a hard exterior surface, similar to a starfish. Does anyone know if this has been studied?
Do lettuce nudibranchs require quarantine?

I don't know that this exact species has been studies but there is no reason to think that Ich or Velvet will encyst on it since, as you point out, it doesn't have a hard surface.
There are 2 risks with soft inverts. Water carryover that they are shipped in and the release of water they may store.

No reason at all to think lettuce nudis themselves carry fish parasites. But many people choose to err on the side of abundant caution.

these little guys are cool. i’ve tried them twice to also address GHA. they got to work right away. however both attempts failed for me. (sadly, they all disappeared by week’s end ... i think my own blood fire shrimp or my stenopus might have a taste for molluscs).
i didn’t quarantine either time.

I've had that one bookmarked for about a year, lots of great info that I've used as the basis for my invert quartile procedure. But sea slugs are 'unkown' in the chart, I was just hoping maybe there had been some new information since then.
I guess it's down to a risk tolerance question. They seem less likely to be carriers of encrusted tomonts, but nobody knows for certain, so it might..
I'll have to mull this one over- it's probably fine, but I have to weigh that against needing to go fallow. Which-as has been pointed out, is probably unlikely.
Rick- you bring up a great point on lifespan that I hadn't thought about. I'll have to look into that a bit further.
Thanks all for your replies!

I have bought groups of 5 or 6 a few times, to take on very small patches of bryopsis in 100g.
Have never quarantined them, just acclimate and then rinse in tank water, place each individually in the aquarium.
They are pretty good at eating the algae, but eventually they all vanish after 4 to 6 weeks.
Whether it's starvation, predation by wrasse or basslet, predation by fire shrimp or banded coral shrimp, going into the overflow, or some combination, I can't say.

When in doubt, I go for the 76 day QT for all soft tissue additions to my DT. I've worked too hard creating a healthy DT.
