Can someone ID this hitch hiker?

So I attempted to extract the mantis using the methods listed in this link

I didnt try the freshwater dip, however I tried the "shake violently" method. This guy will not come out! I also tried the carbonated water method since I have a sodastream unit at my house. I was able to force out alot of amphipods but NO mantis

Oh, and my little brother ended up smashing the LR into 4 pieces, and NOTHING!

I just fed the tank, and saw the little mantis peek his head out, so I snagged that LR out of the tank. I set another bottle trap over night (nothing this AM)

Guess I have to wait it out and see if I hear anymore clicking
