I had a supposedly communal species give me an instance of cannibalism in L1, so I prefer separating them ASAP, and I know where I can get the condiment cups I use at this size but I don't have a lot of time to go shopping so for the most part I work with what I have available (I also really don't have time to set a bunch of stuff up beforehand, or a place to store them; one of my focus interests is carnivorous plants, and I have somewhere around 3,000 of those to take care of). 100 were separated individually, another 42 in groups of 3 in some larger containers, and there are still at least 50 + in the original container so I'm going to just try and keep them topped off on fruit flies and hope to sell a fair number quickly once they hit L2
