Is it a mold in my scoby?

This does in fact look like mold. I would recommend removing the scoby and letting it continue to ferment. If it returns quickly, you may need to toss this batch and start again.

You could remove the scoby by skimming with a sieve or you could pour the liquid out of this container and use something(clean hand) or sieve to catch the scoby. The first option is probably best.

Have you been covering the container with some kind of cheese cloth or breathable lid? In general, that is recommended as it will catch most stuff floating through air, allowing your ferment to develop more safely.
