Is this plant hornwort?

The leaf "opening and closing" also occurs with Hygrophila difformis.

I planted Hygrophila difformis before, it does not open and close leh bro.....it reason why it cease to exist is mainly because my fish tends to eat them off. So I usually will test a number of plants and see which one they don't eat it off. That is the main reason I do not dare to try those expensive ones. :P It's like throwing money into the tank.

It does in my tank. Low light the upper leaves curl inwards. Bright lights they spread out fully. It's not a nutritional deficiency but it's how the plant reacts to light. Some terrestrial plants do this also.

Hmmm....interesting observation. I should have a lot of tanks to play with later on...ha ha...

Yup, it can be very frust. My Tetras used to nip off all the top leaves of of my Nana Petites..

@bluewhale - nice set up you have there.

Thank you very much. That's a casual setup, for those who are serious (as in competition), they have nicer setup than mine. Always looking at them for inspiration for future. There are more out there, you need to google image them out. Hard to tell you which one is good, because beauty is always in the eyes of the beholder.

It is Cabomba, and very fragile. These are fast growing stem plants, not sure if they're as good as hornworts in sucking out nitrates. In water conditions not to their liking, the leaves will break apart and the whole plant will melt and cause a big mess.

That sounds like Hornwort too.

Cabomba/fanworts would have whitish roots. Hornworts is a floater and doesn't have roots.

[Trichopsis]

One main feature I use to distinguish hornwort from the other fine-leaved plants is that when intact, the leaflets tend to bunch together, giving the stalk the appearance of a tapered tip. This is why it's also known as 'coontail' due to the similarity in shape to a raccoon's tail. (See here for an example)
