Super- olives and waters are 2 entirely different snakes, but I have both- they are definitely my favorites in my collection.
I think many young pythons are/can be very snappy (my olive was a HELLION as a youngster), but is PURE joy now, and totally trustworthy with my kids.
An olive or a water may not be the best first snake, but both are DEFINITELY a very rewarding species to keep! I find that I handle my olive and water pair more often than any other of my snakes, including my carpets...
