Thanks for the info. After reading M Kaplins page I am guessing that he may have got hold of a too large cricket. He's in the same tank as larger HL's so I feed a variety of sizes. The fact that the symtoms seem to pass after a day or so supports this. This lizard is the smallest of the bunch at 2 grams.
If this is the actual cause it does support feeding prey items that match the lizard, and a good arguement for seperating hatchlings by size as they grow. The largest in the group is now about 6 grams. Quite a size difference.
