Thesw are some pictures of my ackie, sharky. I am thinking he is male because of the spurs by his vent, bu without a confirmed male/female to compare him to, I can't be sure. I got him for christmas, so I've had him for a little over a month, and in that time he has grown over 2 inches, for a total length of 13 inches! He eats crickets like crazy and has even tackled a few f/t fuzzies!
