Please help with some more plant ID

I Got these from my LFS. Does anybody know what they are?



I suspect 'Ceratopteris thalictroides' and 'Bacopa monnieri', but I don't know nearly enough to be sure. Both of them have lots of separate stalks in there, not a single plant.

 

1st onE ambulia.

 

I'd agree with that rather than ambulia - my ambulia's leaf structure is different, the leaves divide only at the stem, not further on.

Sorry, don't know the 2nd one - I've never had a bacopa.

 

Im sure thats ambulia and not watersprite. Have both in one tank. Amulia looks like that in lowe light levels. With a bit of ferts and light it wil look beter.

 

@tracyp, @KillerBunny. First plant is Ambulia. Watersprite doesn't have a round crown structure like ambulia, hornwort, elodea etc.

 

Here is a pic of Ambulia @KillerBunny.

 

The left plant is Limnophila sessiliflora, the old name of which was Ambulia sessiliflora. So if you want to refer to this plant correctly it is Limnophila. It is definitely not Ceratopteris. TracyP why it looks different to your plant is because the plant has been grown above water, yours have been growing below water as is shown in the pic posted by Slomo.

The right plant has been grown above water and is Hygrophila polysperma, not Bacopa monnieri.

Because these plants have been grown above water, you can expect that they will soon throw off most of their leaves soon but if you look after them they will sprought new shoots and grow below the water.

Kind regards,

Thanx @Dirk for the info. Something new learned today

 

Thanks everybody. Guess I was right (about not knowing enough). Thanks @Dirk. Good to know what to expect.

 

I've been looking at the care of these two plants and just want to confirm what I see. I'm putting them in my 4ft tank which has PFP with Nutrifeed and some nails for iron capped with gravel. As far as I can see, that would be adequate as long as I have good light.

Am I correct in saying that the only thing I really need to successfully grow these would be high light, but that water column ferts and CO2 would help? I've only got a 30W T8 tube at the moment, but will likely get a dual 0.9m T5 ballast soon.

 

No, I would advise water column ferts as well. They are fast growing and cannot get nutrients out of the PFP fast enough. The PFP serves as an excellent reserve source of ferts for the roots and to some extent for the above gravel parts, but the water column ferts are necessary because they grow so fast.

Kind regards,

Dirk

 

Thanks Dirk, I've sent you a PM about getting some DSD from you.
