[Killietalk] freshwater rotifers

[Alberto Restrepo Ubach <restrepo at sandiego_edu>]

Does anybody out there use freshwater rotifers to feed very small 
fry?  I am talking about 'Monostyla' and 'Philodina' [sp?].  How do 
they compare to, say, 'Paramecium multimicronucleatum' in size and 
nutritional value?  I've always used paramecium for tiny fry, but 
recently got my hands on some rotifers and was wondering if they are 
a fry food worth culturing.  If they are, does anybody have any 
suggestions on what to feed the culture?  Somebody suggested 
Micro-vert, a Kent Marine product described as "invertebrate food for 
fine filter feeders".  Is that right?

I was going to try these rotifers on my annulatus (although I got 
them primarily as I branch out from killies and try breed some 
Microgeophagus ramirezi).  The annulatus fry have done well enough 
for years on paramecium and a little neglect, but I though it would 
be, if nothing else, interesting to try other food sources.  Any 
thoughts?
