How long could a Scarlet Badis go without food?

Hey all,
I've had 4 Scarlet Badis in my tank for 2 weeks. I don't feed them at all but they seem to be doing OK. How long can they go without food?

They might be eating. This tank has MTSs, pond snails, res cherries and maybe even blackworms (I put a big bunch in the tank a while ago but I have no idea if they're still in there). I also feed pellet twice daily.

My plan was to see how they're doing without live or frozen food before starting to buy these but I don't know how to tell whether they're OK with their current feeding situation.

Here's one of the little guys:

 

If you put a big bunch of blackworms in your planted tank a while ago then there is definitely a breeding population in your substrate.

That's the hope. It was definitely the goal when I put them in. But I never see them and I worry that the Hexazona Barbs or the Endlers might have gotten to all of them.

I did the same thing many months ago and there are blackworms in my aqua soil substrate (ADA Amazonia). When I uproot plants I often see them and every once in a while I randomly see one wriggling straight up the water column and then usually right into the mouth of my fish.

All the blackworms I see are super tiny though compared to the ones I originally put into the tank. And I mean really small, like the length and width of a quarter inch piece of nylon thread- if that.. So if you've only got your eye open for big ol' blackworms like the ones you originally put in the tank you may be missing them when they're right in front of you. Don't know if it's because the bigger ones are deeper in the substrate or if the big ones get eaten or what.

Cool, I'll keep an eye out for teeny tiny worms then So that didn't really answer my question but I can hope that the dario darios are eating something then.
