Is a too big Enclosure bad??
So I'm planning on buying a L2 3 Giant indian Mantis got a nice Deli Cup planned with a mesh lid and cross ventilation. But as a Main Enclosure I have a 33x43x35 Diy Box planned with 35 cm being the height. I researched and saw that the mantis would only be able to live in the Cup up until l5. So I thought I would be able to move it to the big box but I guess according to some people it's not good for the mantis, what do y'all think, would the box be appropriate for when he outgrows the Cup.
