They're Pycnogonids (taxonomic class Pycnogonida) - not much that is known to eat these that could be safely put in a reef tank.
Actually am planning to keep a pair of bluethroat triggers in this tank, which are reef safe (apart from inverts lol) though I would have to keep them well fed so they don't unearth my trachyphyllias.... though would they be able to reach the spiders out of crevices?
I've been fighting this battle for months now trust me I know. Remarkably every coral (exept 2) have been given the standard 15 min iodine dip and I still managed to get them. I think this is the 5th one over 3 months I've killed.
Probably not. They might eat them when they're exposed to feed though. That said, with Bluethroat Triggers (assuming you're meaning Xanthichthys auromarginatus and not Sufflamen albicaudatum), I've heard these are just about as reef safe as trigger come, with some people even reporting them being fine with shrimp and such in the tank (they're planktivores, so they strongly prefer pods, to my understanding; sea spiders may be larger than they'd like).
Iodine not very effective- Coral RX or revive
Been looking to get a pair of them! Though that has proven to be alot harder than I anticipated. Though the sea spiders are probably about 1 cm in legspan
And I assume aggressive means eats flasher wrasse and anthias and rock moving includes all sandbed coral?
Maybe on the first and definitely on the second. Mine is fine so long as no one messes with its shell stack. Also he’s has a shiv.
Young female. The juvenile has longer antlers, more spots and is greener. As it ages it loses the antlers, gets the white face and black body, and gets the psychopath eyes.
Yeah, for anyone curious, the best I've been able to do is narrow these spiders down to two families - the Nymphonidae family or the Callipallenidae family.
