Riccia Or Glosso?

[Jer-]

Hi

If you were able to grow both, which one would you prefer as a carpet in ur tank?

I can only speak of experience with one - so mine view is scewed.
But I would never keep Riccia again - the bits that break off and constantly float around are too much effort to try and deal with that nifty floating ring didn't work for me and I just got fed-up with green bits just literally everywhere. Mine pearled constantly and all that, but just never became anything like the stunning Riccia Jimboo has.
I believe dwarf Riccia is slightly different, but still..... alas not for me

^ similar experience here. Riccia is probably more aesthetically appealing with its wonderful sparkling oxygen bubbles (I've never known any other plant to pearl so much). I would say it is higher maintenance though.

Glosso is probably easier to look after (providing you have sufficient light, CO2 etc.) and less maintenance. Although it does need completely removing and re-planting after a few months as the lower leaves become starved of light and rot.

So it depends on how much spare time you have and what look you prefer. Jimbooo has the best example of a Riccia lawn, I have a good example of a glosso lawn. See our journals for photos.
