Ok so I've been reading about feeding my Neps, and I just went out and bought some freeze dried bloodworms. I was planning on feeding some to my new Neps that I just received, but they do not have anymore digestive fluid in them due to shipping or what not. If I just fill the pitchers up with some water will that act as digesting fluid, or do the plants have some special formula that they make for themselves? Also, if I do this, how full do the digestive fluids usually fill the pitchers? 1/4? 1/2? less? more? Thanks for any replies!!
