I didn't write the original post you have responded too, but I have 
recently discovered aphids galore on the frogbit in two of my tanks.  I 
have had springtails in the past, but only in tanks with young fry.  As 
soon as the fry are patrolling the tank, the springtails dissappear.  Not 
true with the aphids; the Apistogramma  borellii juveniles won't eat them 
(yet?) and juvenile angels aren't thrilled with them either.  I've tried 
dunking them, but aphids are quite prolific (hell, as I remember they don't 
even need to have sex!) and it doesn't seem to put a dent in the population.
Any other control ideas out there?
