Orchid mantis, throwing up

[TheYellowMantis]

I’ve recently had a orchid mantis arrive in the post, the pot that it came in had some brown liquid inside it, I had a suspicion at this point that the mantis was sick, I housed the mantis in its new enclosure and woke up this morning to more brown liquid in the enclosure, I fed it a fruit fly yesterday. 
 

Any ideas on the best course of action?

Honey water. Also, contact the seller and ask for a new one or a refund if the mantis dies.
