Need Some Advice

[This Old Spouse]

Hey, all,
 
I'm going out of town next Friday for 3 days to open up our lake cabin (yep, even with ice still on the lake). 
 
Here's the thing. I have a 5g tank full of bronze cory fry who will be almost 3 weeks old when I leave. I've already cut down feeding from 3x a day to 2x. But of course I'm terrified to leave them without food for 3 days. Well, 2 and a half days, really. 
 
The tank has a big wad of java moss that I think they should be able to scrounge from, the RCS will keep the tank fairly clean. The rest of the tanks don't concern me, as I've left them for more than a week at a time before with absolutely no problems. I'll give it a water change before I leave.
 
Should I be worried?

I'd add an extra mass of java fern if you have it, but they should be fine. There's far more micro fauna available than you probably realize that they can feed on.

They'll be fine, I left 3 week old fry for nearly a week with no losses, they can feed on the insuforia in the tank while you're away
