[urville]

okay i know this taboo to everything with tanks... shhhh. i dont care

can you id this plant. it grows like crazy only if it's got standing water or high humidity. seriously it carpets like mad!
i was considering it if it can withstand being submerged. time to do a bioassay.

I think it's called duckweed.

I saw your second pic after I posted.
It's not duckweed, sorry.

Looks like some sort of pennywort.

in a couple of applications i saw some people growing it in a hyumid greenhouse and it yellowed a little in spots it grew twice as small and twice as close as in the picture it was a mat you had to tear, but no one actually knows what it is. it must be a runner plant just looking at it, and it readily will grow onto anything, and over anything.

It looks like it might be a plant commonly called Baby's Tears The scientific name I have seen as Micranthemum umbrosum, Helxine soleirolii, and Soleirolia soleirolii, so there may be multiple similar species. It is on the Florida invasive species list also. HTH
