You can feed them any kind of insect, but only insects. If the brine shrimp aren’t alive, then a Venus flytrap won’t digest them. They need live prey to signal them to close, seal and digest. You might be able to feed the brine shrimp to the pitcher plant, but be careful to make sure that they don’t have salt in them. Salt will kill any carnivorous plant.

first thing is that you have to be really careful with growing VFP cause it needs kinda special treatments which include light water soil…

the most important thing is that you have to feed the plant only with bugs and nothing else, cause some of carnivorous plants fans tried method of feeding with meet like pork or chicken- and that was really stupid… You have to feed it with bugs which do not ”wear” shell cause plant cant swallow the shell… perfect bugs for flytrap are bees, ants, fly and little worms … your plants should live really comfortably after that treatment…
