Spiral vals grow tall. I don't know how you would use them as a carpet plant. Many tanks like this have UG, or HC or dwarf hair grass. Marsilea is a nice plant too. Check out the plantfinder and see what look you like. BTW Nice start!
tex gal- i believe he was thinking putting them in the back.
ara35- i would say hc or hm or any moss, or microsword, or if you have really high lighting ,glosso. Either way you cant go wrong with any of these choices as far as carpeting goes. And spiral vals sound good, although i use vallisneria nana in my setup, i should try spirals though,hmmm...
PS: I think the blyxa would look really good around those rocks, just sayin.
move them to another tank ? or forget foreground plants, and put sand instead, sand looks very attractive too. I have cories too, and they dont really seem to disturb my plants too much to uproot them, plus it gets harder to pull out plants when they have long healthy roots. I personally, when i encounter that problem with fish and plants , think of the plants like a tree, a young tree will be easily yanked out or damaged, while a big mature tree will be hard with the size and roots extending far into the ground to anchor it down. I would say let the plants grow by seperating the cories if you have another tank, then once ur carpet is done, put them back in.
ok, I don't know much about cories-just that they tend to pull up plants somehow- but what about a large mat of moss? If you use a large screen of moss, I wouldn't think that they could tear it up. Kind of like the weed sheets you put down for landscaping. I dunno if that is actually feasible. just thinkin
Anything is possible as long as your willing to give it a try.
I have Blyxa japonica and I woldn´t consider it hard to take care of, moderate I would say. Co2 and high lightning isn´t necessary to promote growth. Important though is that the water is soft and that the substrate is nutrition-rich. The height varies from setup to setup, 7-15cm.
Sagittaria subulata might work aswell and that spiecies spreads more rapidly.
heres the thing, i like the idea of having some blyxa and (not or) sagittaria subulata in the foreground at the base of the rocks and leave the valley unplanted to make it a real focal point. the problem now would be a background plant. i think vallisneria looks to similar to these plants and would just look like overkill in my opinion. i think java fern might work well but i dont know what to tie it down to. i was also considering a type of moss covering the rocks but i think the reddish tint of the rocks will be a nice contrast to the green plants where as moss would just make the whole tank green. i ordered my light (it'll be here next tues) and i got my diy working (just waiting for plants to start it back up again). also, another question is how hard would this be to move in about 9 months. it is worth it to put the money into if i have to move back home right?
