ALL GLORY TO HYPNOTOAD!!!
One of the greatest things about building a Tyranids army (or at least when I played during 3rd/4th/5th edition) is that you can more or less do whatever color scheme you enjoy the most. There are more than a handful ideas out there based on the different Tyranid Fleets in the lore though. Also agreed that this person's doing one bangup of a job!
If you ain't 3rd you're... 5th?
Nepenthes x Lady Luck and Drosera x Spatulata after moving into 1/2 perlite and peat moss. Roughly cut away and then sanded some planters with very small built in reservoirs.
Have a Venus flytrap and saracennia purpea x purpea that need a repotting but I overwintered them a couple weeks too long.
It's like they say: "Where there's a whip there's a way"
