How many do you have, and what species? I usually feed them fruit flies, but one tank I didn't feed them , and within two days of hatching, they were eating each other...
Several of my ooths have hatched and I have put some nymphs outside to observe them. They are eating any insect they come across. While I have read they do not like ladybugs.. they seem to findvery young ladybug nymphs quite tasty. They are easy prey for spiders and birds though and my main concern is how they will survive their first molt. i guess they do it in the wild all the time though.. eh?
