Re: Tubifex (was LFD V2 #333
The potato as food for Tubifex is mentioned in Lutz, Welch & Galtsoff's
"Culture Methods for Invertebrate Animals" (1937), but only as an
example of "organic matter" that the worms will eat, along with cow
I have fed Tubifex with ground-up dry cat food, but overfeeding easily
leads to complete oxygen depletion and a crash of the culture. It seems
that Tubifex can live at *almost* 0% O2 saturation, but not in anoxic
conditions. (Perhaps not crushing the pellets, but just burrying them in
the mud, would work better, offering less surface area to bacteria, i.e.
slowing down the decomposition and oxygen depletion. Have to try it.)
