I have a freshly molted adult Spiny Flower that is ready to move to a new enclosure. I have a 2.5 gallon aquarium that I made a custom lid to and drilled vent holes around 3 side. Is this enough ventilation?
An aquarium of that size I would think that every time you opened the lid would move enough air for a few days , even without the holes. That said the more the better for some species .... cheers , Serle
@ky_mantis Unless you plan on keeping the substrate moist it should be fine. If you do develop excess moisture/humidity adding some holes down low above the substrate will take care of it, and add cross-ventilation.
I house my mantids in home made of Lego, I have about that many holes as I use some technical bricks at the top and bottom. I've never had a single mismoult or mould issue. I do open the lids every day to say hello to them and wave a bit of fresh air in though.
My only heastitation would be that it could be hard for them to have good grip. I would suggest lining the top with toole or netting to make sure that your mantis has enough grip. Other than that, it looks like a great enclosure! Good job!
