Ideally I would've gone straight to DWC after hatching, but I needed to keep them alive and growing long enough to get everything set up so they went in 4" cubes until then. My net pots kept getting lost in the mail, I ended up ordering them 3 times before one order arrived lol. I'll keep an eye out for oily reservoir and add in some H2O2 for now. Is that like a paper or plastic you've got on your lids?
