Newly molted.

Cool

I have been puzzling over this photo so could you answer these questions please?
1/ Why is the T in an otherwise empty bottle?
2/ You say it is freshly moulted which is obvious by its still white fangs so did it moult in that bottle or have you been messing with a still unhardened T?

@Enn49 I desperately needed to get the substrate changed because I had a mold problem. Don't be mislead by the camera flash reflection on the fangs...

Also, that's a catch cup, not an empty bottle.

Wouldn't it be easier to use a catch cup instead of a bottle with a narrow neck?

There a hole that I burned into the cap so I can use a small brush to coax them out.

The irony................

@Tnoob If it's a catch cup how do you drop it over an escaping T?

@Enn49 I think it's cut out at the bottom to be fair

It's a plastic bottle that's been cut in half.
