It never occurred to me to wonder but, now that you mention it, I have
duckweed in all my tanks except the two that have pl*cos in them. Usually,
the duckweed and riccia grow all mixed up together but, in the high-light
tank with the royal pl*co in it, there is only riccia. I'm not sure how to
check since they never even move, let alone eat, if they think I might be
looking at them.

Plecos certainly love green stuff. Anyone know, from experience,
whether
they'll eat duckweek?
