Something went wrong no doubt. How big was this Boiga and how deep was the water? Temp/depth of water? How long did you leave it in there? I just soaked a 6' female Melanota in a 3' trash can w/1' of water in it...45 minutes max. Their skin is so thin that no more than that is necessary.

Your comment about treating them "several times" concerns me. My imports are treated after 90 days or so and only after at least 6 solid feedings. I only treat twice, 5 days apart w/Panacur and Flagyl. Sometines w/imports it ends up being an "oh well" situation wherein a snake rolls w/no discernable event to pin it on.
