Stretchy tongue

[Pickle-cham]

Tongue length & stretchiness as an indication of overall health, im wanting to know what the ideal is 1 times or 1.5 times body length?

It depends on how far away the bug is. If they miss, then you should be concerned. I believe they can extend their tongues up to twice their body length.
