Hi and welcome to the forum.
I'm also into aquaponics, but have yet to stick any carnivorous plants in my system. I love how easy it is to grow things in this type of system. So much easier than ground crops. What type of media do you use? I've been thinking about testing out a small system using sand. I think some of the smaller plants like the droseras would do better in this rather than the lava rocks I use now for vegetables.
Do you have pictures of your set up? I'd love to see if you do
