What fish will eat duckweed?
After getting some dime-sized baby angels, I used a couple of sponges to dampen the flow from my HOB since they can't tolerate too much water agitation. Within a week, I had an outbreak of duckweed I didn't know I had. Appeared out of nowhere. Guess the surface agitation from the HOB had kept them from multiplying. But now....
I've heard mollies will eat duckweed. Will they, and not munch on other plants as well? If so, any particular varieties/species that are better than others? I like the colorful Gold Dust Mollies--which are supposedly a variety of P. sphenops. But the only local source is Petco, and I'm terrified of introducing any pathogens to my baby angels. Don't have a quarantine tank set up, but I could quarantine 2-3 in a 5 gal bucket with some plants for a month if I had to--and I could be assured they'd do their job of duckweed control to make it worth the hassle
I like the idea of having some livebearers with my angels as their fry will provide a study supply of live food for them. Already have a host of guppies, but they don't seem to have any appetite for duckweed, sadly.
Any suggestions/experience welcomed--thanks!
