Psytalla Horrida Communal Care

[TarynElliott]

I recently bought a few horrid king assassin bug nymphs and everything seems to be okay for what I can tell as they're eating okay.
Could anyone tell me how many I can keep in a 24.5 x 37 x 22cm (9.6" x 14.5" x 8.6") enclosure when they start hitting adult size. Also any general input appreciated as I've never kept assassin bugs.

Ten would be reasonable numbers to keep in that size.

I’ve kept around twelve adults in about pretty close size enclosure previously.

Vertical cork bark pieces are important. They molt hanging down from them, so they need some height. I keep mine very slightly moist with a water dish. If you want babies, keep one area of the substrate more moist. They lay their eggs in there.
They are somewhat messy eaters, so make sure to remove prey carcasses often, or it can get smelly in there.
Overall, they are fun. Curious, great hunters, but not the slightest aggression towards the keeper's tongs or hands.

Edit: their molting is something to behold. You'll see...
