Just to add to the list, the Mexican rainbow cichlid (Herotilapia
multispinosa) is also a good duckweed grazer. A medium-small cichlid that is
so prolific it can show up convicts, there were actually so many fry they
became Epiplatys food (but make sure the fry are very young so that the
unpaired fins are not a problem).
A couple small rainbow cichlids could be put into a duckweed infested tank
to forage for a while. Unfed they will seek out the duckweed. When they
began to clean off the other stuff, they had already snarfed up the duckweed
and it is time to move them on to another tank and plunk a pair of killies
into the now purged set-up.
All the best,
Scott of the smooth arms
