Arrow crabs and wrasses big and small

[JoJosReef]

I have loads of bristleworms. Don't see them as a problem. But they'd be a bountiful food source for an arrow crab, which I find an curiosity for a reef tank. Anyone have experience with arrow crabs and wrasses? My tank will be wrasse dominant, including leopard(s), medium-small Halichoeres wrasses (yellow and radiant), pencil wrasse(s) (splendens and potentially severnsi), 2x pink streak wrasses (my small ones), and a mix of flashers and fairies. Tank also has a Yasha goby/pistol pair.

Cool looking dude.

Anyone have experience with these and think there may be some problems between the wrasses targeting the arrow crab or the arrow crab targeting the wrasses? Thanks!

Dude arrow crabs are scary looking. Saw one in a friends tank he said it goes after fish too but his fish are too quick for it.

Yeah, I don't like the idea of an arrow crab after my pinkies or my yasha. The pinkies don't do well with aggression. Probably pass.

Yasha especially seems like it'd be eventually lunch. Halichoeres wrasse grow fairly quickly, and when full grown they're very effective bristleworm predators. I'm also surprised your pink streaks don't help keep the population down a bit. I know my yellow banded possum eats the small bristleworms all day.

They might, but I have some massive bristleworms. Far too big for them. I have a pencil wrasse that is about 4" that might be eating some, too. I never see it, but caught a glimpse of it today and it didn't look skinny. Must be eating something.
