I have recently acquire a pot of vft. I noticed that some of the trap have a slightly blackish side. I place it near the window to enable it to have sufficient sunlight. What do i have to do to make sure it grows well? Do i nd to place insects for it to eat? (I heard they thrive on neglect) . i noticed some traps have closed but there does not seem to have any insect inside. Is this a bad sign? does constant pruning is needed. i plan to get more cps. Are vft encourged to keep in a tank wth others cps or vfts? or do they survive better indiviually potted? Thanks for your help
