View Full Version : seagrass ID

04/17/2013, 02:35 AM
hey there!

i got lucky yesterday, someone in my city ordered seagrasses, and they delivered too much. so i got to take one portion of it, and it turns out that there are 3 different species in the mix.


one is a halophila species, but the other 2 are hard to ID for me :) delivery is said to have come from SE Asia. i found that halophila minor is sometimes associated with halodule pinifolia, so this could be a hint, as the 3 species came with tangled roots.

it took some time to sort out the roots and dead stuff without harming the rhizomes, and now i got them seperated by species. they are going into my fuge, where i already have a not so thriving mediterranean cymodocea nodosa and caulerpa prolifera.

i also consider putting some in the display, as i have so many, at least of the very thin one, with leaves around 1mm. also some of the halophila will go in the display, lets see how it does, as it is said to be an easier one.

if someone could please help me with identifying, that would be great!

thanks in advance, martin

planted them, even filled a small rubbermaid with sand/mud. also tried to ID them, according to http://www.seagrasswatch.org/id_seagrass.html i have halodule uninervis & pinifolia (the very thin one), and halophila ovalis





i hope they start to grow, i am already considering setting up a special tank, although it would take some time for the substrate to be ready.

greetings, martin

order came over a wholesaler in europe, to someone in my reefcommunity. its said to have come from SE asia, and the 3 seagrasses were mixed and tangled in the shipment, so i guess they were harvested together. finding a LFS that might take special orders could be crucial, where i live its possible to order seagrass from wholesalers, and the LFS is willing to do so if you manage to find others to join the order.

i already counted 4 fresh halophila leaves! the halodule pinifolia is also growing, but hard to see wether they also form new leaves as they are too many and thin.

my old cymodocea nodosa is also growing new leaves, but no sign of sprouting new shoots.

some growth. halophila developed quite a few new leaves, even on new nodes which could show rhizome growth. the two halodule grew new leaves on existing nodes. uninervis, the bigger one, grows slower.

the seagrasses i planted in the shallow sandbed in the display also produced new leaves but also got dug out to a certain degree and were replanted.

The upper left should be Zostera marina.
slow grower!!
I got it from Japan and died within 6 months after I plant it in my tank.

I hope they grow too. Can't wait to be able to start a grass/horse tank. Or maybe just grass.
