I've replaced the peace lily with another fern, it looks so nice growing out the top of the tank along with a Kawakawa and it seems like such a shame to have to put a lid on it (squishing the plants down in the process) in order to add live food for the frogs. Does anyone have a lidless terrarium or have any ideas how we could keep both looks and still be able to add live food without it just crawling or flying right out, and of course stopping the frogs from just climbing up and out?
