mating scorpions

I have 3 scorpions in thesame tank, i think that their is 1 male and 2 females.

Over the last week i have discovered some white fluidy substance in the tank a couple of times, I was just wondering whether anyone could tell me what the sperm sack looks like. Because i'm not sure if they have been mating or not.

I think thats poo

If it doesn't look like that, it's poo

As said above, you're seeing poo.

Are you SURE that you have 1.2.0? If there's any doubt, put up a shot of the pectines and we can confirm / deny this.

Here's a good shot of a scorpion spermataphore:
