Dan, others more knowledgeable than I have commented on the egg/sperm
transmission through filter flow problem. The only thing I would add to
this is that it *is* entirely possible to transfer eggs via a net used to
feed live food from one tank to the next. I know of a case of a guy who
ended up with all his different Fp. gardneri killies looking the same
after a few generations - pretty fish they were too, but hybrids
nevertheless. They were on the same recirculating filter but in different
tanks. He thought it might be sperm transmission via flow for a while but
eventually came to the conclusion that it was eggs via net.
Cheers, Andrew
