How long can salamander larvae go without food?

[kp2000]

I have some spotted salamander larvae that are around 7 weeks old. I’ll be gone for about 10 days and was wondering if they’d be alright if I left a lot black worms in. There’s a filter and I’ve only ever had them on black worms.

Live or frozen?

I usually leave frozen in for 15-30 minutes before taking it out, leaving food in there for a while can grow mold, and affect your water parameters.

I have only ever fed them live.
