stunted Taiwan / needle leave java ferns

[mkt]

Hi - my java ferns look stunted - almost like they are having anthritis.
The leaves do not grow straight and curve in funny ways.

They almost look like they aren't growing.

Has anyone experienced the same?

Any ideas? suggestions?
Many thanks!

What's your tank temp?

Hi - sorry did not get the pic.
My tank's temp is 24 C
PH is 6.4-6.6

I would have thought that java ferns whatever species would be easy to grow .....everything else grows well except this fern

Yup... Facing the same here... So what is the cause?

[David]

by the looks of your PH around 6.4 to 6.6, your KH could be low...perhaps around 3 to 4? based on pass experience ferns do better with KH5 at PH level of around 6.7 to 6.8...best at neutral?

Are you dosing your water column with any liquid fert?

[mkt]

i want the KH to be low ....for shrimps....
And yeah i am dosing the water column - everything does well including bolbitis except the darn fern.

just moved them out of sight and out of mind maybe check in a couple of months.....
