I strongly don't rec- hold on
we have dozens of them in our shark ponds filter Refugium it’s about 1000 gallons with a lot of live rock in there. ga e up trying to remove them years ago. they breed plenty
This I gotta see, are they o. scyllarus or the smaller hitchhikers? That sounds amazing, especially if they're breeding in there cause there has only been 1 known case of a stomatopod settling in captivity (a G. chiragra), all planktonic specimens die. That would be a lead to a break through if they're actually in an ecosystem actively multiplying.

I strongly don't recommend keeping a pair in captivity. Its actually not unheard of for pairs of Odontodactylus in general to exist, and many have done it but usually its temporary, they form pairs and then split off before aggression occurs. In a giant system I suppose its not much different than the ocean. Its really not
that hard to breed them, rearing the eggs past larval stage is borderline impossible but to get fertile eggs its surprisingly not that complicated and easier than a lot of animals in the pet trade (probably easier than doing it with tarantulas).
Stars have to align a bit for this behavior and sometimes the stress of another's presence gets to them. The only species I know will actually form monogamous pairs are lysiosquillids (zebra mantis and friends) where the female will stay in the burrow and the male will actively hunt and bring her food. We could actually have had a huge market of L. maculata pairs being sold and kept but divers do not dig deep enough into their burrows to collect the female, hence the over abundance of males.
I'm also going to go on a limb here... but I don't think the 2 O. scyllarus in the video are a pair. Looks to me like one claimed dominance of a burrow and the other is lost/hiding from it. My biggest suspicion is the one more in the open is actually a female, which wouldn't make a lot of sense being the one hunting for the male. The one shown in the burrow I can't get a good angle to tell.
