Venus Flytraps need a lot of light to make fully functional traps. Temperatures over 80 degrees also tends to help them with trap speed and closure. After opening, traps typically take a week of so to fully mature, so might close slowly at first. There are simply a host of variables that go into trap closure, so it is impossible to tell what could be affecting the plant at this juncture. So long as it gets as much light as can be supplied, full sun optimal, soft water, moderate temperatures, and no fertilized soil, it should be healthy and begin developing normally. If you just got the plant, it is likely that it is adapting to your new environment, so might be a bit off for a few weeks.

Thanks so much!!!
