I suggested to Wylde in rec.ponds that he post in the *.aquaria
newsgroups since I thought maybe killifish would work here since they
love things like mosquito larvae and will live in quite shallow water.
(Was very impressed by Richard's recent Rivulus story.) Unfortunately,
I don't know enough specifics about killies to suggest any species or be
certain they would work here.
