Hairgrass remaining short!

[|squee|]

Hi all,

I bought my hairgrass sometime in September. It was in emersed form then, and quite short, around 6cm height.

I planted them in my 1.5ft, after I tore up all the Blyxia Japonica that had been growing very well before. I planted them in its place in rather dense intervals.

I also uprooted my glosso bed, and restarted it with a few plantlets of fresh glosso.

The thing is, my hairgrass has been remaining short for all this while now. The newly planted glosso has already begun to spread and bed, yet the hairgrass is not growing tall. Oh, it is putting out lots of new leaves, but these leaves are the same height as the old ones.

Lights are 36W 9 hours daily, DIY c02, base fertilser-ed substrate. These conditions were the same before I uprooted everything, so it makes no sense that the hairgrass is not growing tall.

Could my hairgrass have been dwarf hairgrass that I bought?

It could be dwaft hairgrass you have there...

From what I noticed, those hairgrass from Teo (or Ah Peh) are the longer one whereas those from 'chao guan' are the dwarf version. I have both types in my tank now.

So when I've bought them they should have been quite long? Hmmm... if it's dwarf hairgrass...

I like dwarf hairgrass-- willing to x-change with you if interested

shrimps and some cyprinids (even rainbowfishes! but they tend to pull instead) can keep HG short by nibbling the tip.

Now that's a thought. I have a million cherry shrimps in there...

FeiMiao, will be happy to if I decide to tear it up
