I kept running out of crickets, so today I bought 120. I think I'll be good for a few days....
yeah I ordered 200 (there was no option for 300) but my only issue is I can't find any guides on housing juvie dubias, only for keeping colonies. I have an idea of what do do (horizontally stacking egg crates, what to feed, ventilation and keep at lower temps if you want growth delayed, and humid).
