I'm seeing if anyone would be interested in purchasing some rooted cuttings of water mint (Mentha aquatica)? It makes your aquarium water smell minty fresh and fish and snails leave it alone (in my experience)!
Growth would have to be emersed, I'd imagine. It would probably make a fine riparium or paludarium plant, but wouldn't it get too big? I'm curious and would like to try it, but not sure it would work for me.
How deep do you have it planted in the medium light tank- I've read several accounts of it growing submerged from 10cm- to one site saying 15cm.
You've got it growing submerged planting deeper than that? What do you consider "medium light" and is that a CO2 tank? (I'm assuming the high-light is CO2). I'd suspect in a medium light tank without CO2 it may not survive???
I get about 2.4wpg. I don't have CO2 though- I've got nice mineralized potting soil as the bottom layer of my substrate though- and I'd suspect as a terrestrial plant mint is almost exclusively a root feeder.
Ummm... Let's see. It's in my 15 gallon high aquarium. I have a little more than 3 wpg and no CO2. And my mistake, the other little tank I have it in is high light as well but no CO2 in that either. I think it could do okay in 2.4 wpg.
