I dont have any info that I have found.. but from speaking with peope they are communal and the venom is not that bad. (not like you should get stung tho) and they are supposedly very entertaining because of how they wag their tail to use its sensory organ and size up prey (or so i understand) I have heard mixed reviews.. some say they are great some say they are boring. they are apparently skittish as well.. and that is about all I know aside from the fact that I want some! lol any particular one you like? anyways I hope that helps and I am sure someone will have more info for you. or some corrections at least
Most of my advice is 2nd hand from a friend but Ive been wanting this genus since I got into the hobby not long ago and once the temp warm up, I'll be on my way. They're like beautiful little tanks!
Anyways, many people keep them communally with success but I understand that isolating gravid females in a small container in the dark (to mimic the burrow she would dig) is advisable and is certainly what I will do. Orthochirus scrobiculosus negebensis seems to be the most common in the hobby, along with O.innesi but I imagine many keep them without knowing the exact species.
Gil (wizentrop) has been stung by an adult O.s.negebensis and described it as incredibly painful although he didn't have any systemic symptoms.
He sent me a care sheet for O.s.negebensis which Im sure he would be happy for me to share if you PM me.
I have dozens of Orthochirus s. negebensis and several gravid females of a
species from Pakistan. They are very atractive to keep in groups, and are
active too. The only downside for me is that the young (esp. O. s. negebensis) are very difficult to get in the 3rd instar. I hear this from other people in Europe too. Some lost 90% of the young or more, and so did I..
At first the young did great, but later in the second instar (when normally the
pre-molt stage should start) they started losing weight for some reason. I tried everything I could think of, regarding temperature, moisture, food, substrate, shelter.., but nothing seemed to work
The adults are very easy to keep and a lot of fun. Since last year these are
almost common at Dutch expo's. Most people are disappointed in the size I think and therefore ignore them. I think Orthochirus is great fun, but be careful to buy young!...
