As for the second part is it safe? let's just say i wouldn't have one in my tank, I've " heard " of them nuking tanks if the die, apparently the can release some pretty potent toxins.
I would speculate that it is a cuke also. What is the total length of this animal?
No, no,no keep him they are good from tanks.
Yes fun for sure
