I am really desperate for some help with culturing daphnia moina. I have a large colony of licorice gouramis who don't eat too many live foods well, and daphnia moina is their favorite. I also have six juvenile dwarf puffers who eat only snails and moina despite all my best efforts.
However, my moina cultures crash constantly, and now, in the dead of winter, I can't really get any cultures going at all. I have been working at this since early last summer, so I have tried with maybe thirty different starter cultures. I place the cultures in a five gallon bucket with green water, a gentle airstone, a compact fluoro light, and feed yeast daily or else spirulina.
I have tried different types of water and I have tried different amounts of food, nothing seems to help or really affect the outcome.
Is there anyone on PT with lots of experience culturing moina indoors who can walk me through this?
Maybe I need to quit altogether, but all I have for other live foods are baby brine, blackworms, grindals and microworms - and my licorice won't eat the blackworms and the puffs won't eat the microworms or grindals, so I feel very dependent on the moina.
What am I doing wrong? Or, is there some kind of substitute for moina that would work for very small fish and be easier? (Nothing could be much more trouble!)
Thank you for any feedback,
