semi-aquatics, mondo grass, apongeton

[dslam]

I purchased some "mondo grass" from the LFS today and came home to find out that it is a marsh or bog plant and will only survive submerged for a short period. Some information seems to indicate this could survive for quite a long period of time fully submerged but will eventually need to be emersed for a time in order to recover. Apongeton apparently likes to be removed and rested for a couple of months, emersed, before being submerged again.

Our apongeton is doing absolutely beautifully. I couldn't ask for a more lush and attractive plant really. I would have bought another but the LFS that sells them is slightly crooked IMO (sold us disease along with a fish, disease was free though... losing half our stock wasn't.)

Our tank is very clean and prosperous and I wonder if I might just remove the Mondo if it starts to shed and die, emersing it in some tank water..

So on to questions.. How much water does the Mondo need to be emersed in? How long should I emerse it before submerging again? I can't find particular information on google really, only guesses and information about similar species.
I have grown to trust and appreciate these forums so I would like to hear it from those I trust rather than google a bit more and find contradictory questionable info!

Any info on the Apongeton would be nice as well. If anyone knows approximately how long it tends to grow submerged before needing to rest that would be great.

You can probably get a few month out of the mondo grass before it begins to rot away. I bought it when I first startedf buying plants, but I didn't know that it was not going to live long term.

But if you think of it the same as buying fresh flowers, you'll be happy since it lastsa lot longer than roses. . .

grow it out the top of your filter.

That sounds interesting, could you elaborate? I am using a power filter, should I put it in the bio foam?

im growing lucky bamboo out of my whisper internal. all i did was wedge it between the front of the biofoam and the outlet. w/ a H.O.T. you could have the coming out of the vent holes. you just need to make sure the plant gets indirect lighting as it will be above the aquarium light.
