I brought out my AGB to handle today, after not having done so for a month or two, when I noticed all of his right legs on his first ten or so segments had vanished. Additionally, there were sporadic missing legs until about 1/4th of the way down his body. I have no idea how this happened, and I don't believe he has molted in about a year, but I am not positive. He had all of his legs when I saw him pressed against the side of the glass a month ago, but has been on the surface and under the substrate multiple times since then. I was not given an age when I purchased him, so I don't know how many more molts he has about left, but he is about 10.5". Does anyone have any idea what could have caused this? Also, what are the normal intervals between adult AGB molts? Thanks.
