I'm thinking of getting duckweed myself. Do they do the same things as other plants with the water? Help keep it filtered? I know absolutely nothing about plants :P I've got a little ten gallon tank so I think it'd look nice to have them in there floating on top.
Yes, All plants absorb ammonia. Duckweed is special because it grows like a weed with supernatural powers So it will absorb more than other plants will. I have come across sites and forums where people say they have to throw handfuls of the stuff away every week to keep it under control. I wish I had some but I cant find it anywhere...
I wouldn't mind having to do that :P It's a me-proof plant then LOL. I'm looking at a store online that I could buy some for $11 (shipping included). I may order some on monday :). Right now I have bulbs sitting in the tank (got them two days ago) waiting to see if they grow, java moss, (which I think is branching out, there's like an inch grown over into the water off the left side of it) a lucky bamboo and one other plant I can't remember what it is. I think the duckweed would make it look even better :)
Yeah, duckweed looks cool. But its tiny! Frogbit is another plant. That one looks really pretty! Like miniature lily pads. Actually for duckweed (maybe frogbit) there are some forums dedicated to planted aquariums where people will be willing to give away their extra duckweed (and sometimes other plant clippings) for free. You just have to pay for shipping.
I also have some apongeton bulbs :) Mine took about a week to sprout.
This is ( Insert Name here) in his 1/2 gallon tank. I hope to upgrade to 2.5 gallon tank on Wednesday. He has marbles, gravel, a floating plastic ball, and a plastic plant. I not sure what breed he is. ( I would appreciate someone telling me). He is not very active, and I hope a bigger tank will change that.
