Thanks for your suggestions, Ryan and constant trimming may very well be
what I'm in for here. Khew Sin Sun who has  a website at
http://www.singnet.com.sg/~khewss emailed me Sunday to tell me of some
problems with the Riccia which I was very glad to hear of. His 200g. tank
looks a lot like Amano's, in my opinion.  He says that when Riccia is
trimmed, it floats into other plants, attaches itself and is quite a
nuisance to remove completely. After 3 months it starts to die underneath
due to light loss, becomes detached and starts to float. More trimming
could help possibly but in a very large tank such as he has, I imagine that
would be quite the chore.

I would like some C. japonica in my tanks but I've not seen them in
Toronto. If I ever do, I'll be sure not to put them in with the Riccia.
Thanks very much for your help.
