Peter, are your VFT's kept outside? The closer they mimic "natural" conditions the more likely they will do fine. Kept in terraria, in artificial light, and whatever else a lot of us have done when we were kids with oir erspective first VFT (tap water, no dormancy period, keeping them perpetually covered) adds enough stress to their baseline stress - and puts them over the edge. I did all the afore-mentioned faux pas until I stumbled onto this discussion forum. Mine are kept outside, south-facing, catching their own bugs. They flower... they clump... they live on. Happy ending!
