Thinking about getting some for my 55g, I know most on here don't like it but I had it once before as a hitchhiker and it didn't bother me and had no problem getting rid of it.

Problem is when I had it before I didn't have mollies and now I have 6 of them. Will they eat it faster than it can grow? I know duckweed is a fast grower but I'm only running one T8 48' tube over my 55 so it probably won't grow as fast as normal. I don't want to waste my money if the mollies will chow down and eliminate the duckweed. I planned on getting it from aquarium, it's sold in 2lbs. Don't know how much surface that would cover in a 55

I think 2 lbs would be more than enough. You could also cultivate some of the duckweed outside in bins/tray or on your windowsill in jars, just to make sure you always have some.

Mollies eat duckweed? I kept duckweed in a tank years ago with mollies and don't recall them eating it, but maybe as you question it was just growing fast enough to not notice. When I transferred some of it to my goldfish tank, that was a different story lol.

i know JDM has a overabundance of this, maybe try pming him about roughly how much area 2lbs would cover.

Thanks, I'll do that.

I actually got a bunch yesterday - I was looking for water sprite, which also came in, but it was just luck of the draw scoops of the other person's tank. I will gladly send you the duckweed, just pay the shipping ($6) It's pretty much a quarte sized ziplock full

I used to have duckweed, but considered it a nuisance because it would dry out on the side of the glass because of evaporation, for ruining my filter(and media), and because it sticks to you like glue when you try to get things out of your aquarium. Even when I had it, it never grew on the surface so it was practically dead.

I know it can be a pain but its the only floating plant that has grown for me in past. I've failed with water sprite , pennywort , and currently failing with wisteria. This is a last resort for me as I wants/need a floating plant to provide shade for my many anubias.

Then I would recommend Frogbit if you need it for shade.:-)

If my pennywort died along with my wisteria and water sprite I'm sure not trying frogbit as it is even considered tougher to grow than those mentioned above. Tired of wasting money.
