Will crabs kill green lettuce nudibranches?

The title says it all. Will they?

anyone know the answer to this or where I can find the answer?

I had a Sally Lightfoot with two of them. The crab didn't kill them but my powerheads sure did.

Thanks Nas19320, mine are redlegs and Hawaiian black legs or something like that.

Are you getting the nudis to combat a problem algae issue? IME, none of my crabs bothered any of the GLN's that I had, unfortunately, they solved my bryopsis problem and then died of starvation.

Yes, I have an outbreak of green hair algae. It is probably the result of the tank being recently cycled. But whatever the case, I would like to nip it in the bud. The crabs are doing a pretty good job, I think I just didn't buy enough of them for a 120. I have shut off my lights for the weekend, will see what that does. I have read the green lettuce nudibranches eat hair algae. Do you know if that is correct?

Yes, they do, and very well. THis is how I got rid of mine. But at the same time, once it was all gone, they ate nothing else and pretty much just wasted away.
