I'm not even sure about the lifespan of tubi, nor their reproductive behaviours.. I believe the challenge with tubis is twofold:
1. how to keep the "culture" long enough without smelling/dying off, which is what the OP of this thread has figured, and
2. how "safe" is the batch that you have from diseases/internal parasites..
even if I manage to keep them alive and wriggling after a month and they reproduce, i'm not even sure if it's safe to say that they are free from any diseases since rubbish in, rubbish out
