I currently have two Emperors in separate enclosures due to them displaying a lot of aggression toward each other and even killing a third soon after I got the three of them. When I got them I don't think I had enough hides in their terrariums and that somehow led to the aggressive behavior, but I'm not sure.

I have recently been looking at a 6' x 18" x 18" terrarium that I would like to turn into a communal vivarium using the methodology shown here and here, but would first like to know what I should be doing and should not be doing.

How many Emperors could coexist in such an environment?

Do I need one hide per scorpion? If not, what is the common ratio?

Can I introduce my two formerly aggressive Emperors back into a community tank, or should I keep them separated?

Do I need a certain ratio of males to females? Because Ken the Bug Guy (where I got these three) sent me three males last time and I won't go back to him if I'm going to keep getting improper ratios.

Did I miss any important questions? I'm kind of new to this (a few months into the hobby) so any tips would be appreciated before I drop a few hundred dollars into a new set-up.

Also, if they do get into a stinging fight, will their venom kill each other or is it considered a 1/5 for everything and not just humans? Before I split my pair up they were striking at each other with their tails, but I assumed they were just constantly missing since neither of them fell over dead.

If I see fighting in a communal set-up do I just let it go and hope they settle down, or do I separate them like I did with this murderous pair?

scorpions are immune to their own venom (else they would die holding it in their bodies to sting with) so only danger is the physical damage from being stung and stress/pincher damage, second only buying 3 at a time without requesting a male/female ratio only gives you a very, very low chance of getting a mated pair. before bashing a supplier, we might need to think about the quantity of animals they have (more than the 3 you bought) and the fact you ordered 3, not 2 females/one male or any other ratio, you ordered 3 they sent you 3. since your P. imperitors were fighting then you probably dont have enough area/hides/food for them. how big is the tank you have these 3 in now? and how many hiding places do you have? you should have atleast 1 hide more than the number of scorps but if i had 3 in the same tank i would put atleast 5 hiding spots, that way if one doesnt like the spot hes in, he has a free spot to go to so he doesnt have to fight for a new one.

if you did what i did, it seemed to work

i had a male, wanting to mate and one molt ahead of the female, it only mattered because he treats her incredibly nice despite her being too young to mate, and they sleep together and i hope get along once she molts and mates. she was a total before he pinched her and she calmed down. so yeah, right now, they are sleeping next to each other in the warm corner. its cute :p

that was just my situation, and my scorpions. all have different personalities, and their hunger has alot to do with it.

from all i've been told and read up, put the female(s) in first, to let them settle, then introduce the male at the opposite side of the tank.

i have a 6' x 18" x 18" terrarium and i swear i can only fit in 2 emp scorpions. providing 2 hiding spots and a water dish of course. that alone takes up all the space, they barely have room to run around but i placed the bark and rocks in a way that the scorpions can climb over them giving them more room.

phan, do you have a pic of the enclosure?

looks good...
lol id keep it simple...
i wanted mine to stay simple, but i kept getting ideas...lol

its ok i just got my scorps like not even a week ago haha im just triyng to give it the best environment i can get. but i was wondering if having the 2 hides so close together would cause any problems? and the bark hide that i have, u can see all the way to the back of it as u can see in the picture. should i put substrate and fill up the hole on the other side so it feels like an actual hole? i am just leaving the hide in there for now to see if the 2 scorps would have any problems because they both sleep in the rock one but sometimes the little scorp would go under the bark hide.. dont ask me why LOL

nahh man if theyre not fighting, and actually being civilized towards each other...its perfect...

i wish my 2 males wouldnt have had world war 3 in my big tank, cause now i have to seperate tham and it puts off on me getting a leopard gecko =(
but oh well...theyre my babies and ill do anything possible for my fav pets =)

yeah its actually pretty funny that they dont fight cause the big scorp im assuming he/she is an adult cause it is very lazy and barely goes anywhere. the little one is always moving around and eating crickets. but the thing is, i read somewhere and a guy was housing 2 emp scorps in the same tank and he would just put in crickets and let them roam around until the scorps got hungry and would hunt for them. i was just wondering if this is bad for the scorps or the tank

uhhh....i have no idea...
i wait about 2 weeks in between feedings and than ill toss like 4 crickets each into the tanks and they usually stay right on the edge of their hides waiting for them to get to close...

on a very rare occasion, i can grab a cricket and actually put it in their claws and they'll eat it right away...

everybody on here says not to leave them in for more than 24 hours, so id just follow that general idea...i leave mine in for about 48 becuse my first one always eats 4-5 crickets in that time period...

i think most people say to take out the crickets because it could hurt the scorpions? im not sure..

mine havent had a problem...
but i wont leave crickets in ther longer than 2 days

Leave them in for too long and you cause the risk of springtails, mites or undue amounts of stress to the scorpion (Particularly if it is young)
