Before I purchase one (FD) of these could someone please share any information regarding length of life. What is the longest anyone has heard of someone keeping one alive in their tank?
if you buy the phytoplankton it will tell you how much and how often to pour into your tank. as long as everything stays steady they will live a long life. just make sure that all your levels stay steady and you feed on a regular basis. i dont think there is a specific time length that they live because it all depends on how you care for it and so forth.
