How do you make your top? What material do you use for netting? I am thinking I will need to add a top to my 40B so my clawed frogs don't leap out. :XI prefer 40 dimensions over 55 as well. I don't think anyone sells plastic style hoods for them but I've never looked to hard, light strip and glass versatop or diy 1/4" netting tops have been how I always went with them. Petco does sell a stand that fits them for like $55-60.
