Anyone have any tips and tricks for someone starting their first bioactive enclosure? I've got some corns who would benefit from the upgrade. I tried once before but everything ended up dying... I'd love some help amd support, thanks. (Photos of some of the corns for fun)

My build its 4ftx4ftx2ft home to 6 phyllobates terribilis (yellow)

Working on setting this up for my Cornduran. Feedback?

Bioactive paludarium build I did last year, it has a lot of fish and I think will eventually be a home for some dart frogs.

Wondering what would look good with this set up
