Halcurias carlgreni

[DiscoDon]

Hello,

Last week, I purchased one of these guys not knowing anything about them. All I can find is that they are cold water nems requiring mysis shrimp. Does anyone else have any additional info like water flow, need of a substrate, frequency of feeding, lighting (I am guessing it does not need), tankmates, etc.

Thank you,

Don

I can't find much either, unfortunately.

They're reportedly coldwater (reportedly 66-72F), NPS (requiring daily feedings), have a toxin called Halcurin (which is somewhat ironic since these have been transferred to a new genus, and the official name for these nems is now Isohalcurias carlgreni), they're found at depths ranging from 10-120m, and the only info on their habitat beyond that is that they're habitat is "shelf"* (I don't know if that means reef-shelf or continental-shelf though, and it's vague enough as is).
