I know frogbit is considered a floating plant. but do you think it would be possible to plant it under water as a foreground plant?
Might be silly..
Maybe. Typically floating plants have high co2 demands so you would need to make sure there was plenty of co2 & enough light for it to grow. Anchoring it in the substrate would be an issue to. I doubt it would spread out very well either.
For a similar look I suggest Water Clover (Marsilea Hirsuta) as being a much better option.
Here's some info on it:
Since many floating plants have really short water roots I'm not sure they could take up the nutrients they need . they would also be hard to keep in the substrate.
Nutters suggestion for a substitute is excellent.
When my HOB filter gets one under the water line and it gets caught on decore its leaves begin to turn brown.
Thanks for the suggestion everyone. This stuff grows like weeds so I might just try putting one bunch of it down there and see how it fairs after a couple of days.
