I think thats normal. Mine does the same and I was curious and tried to pull the plant out, and found the plant had rooted pretty well into the substrate.
Some of my repens' roots seem to be growing upwards and out of the soil.
Lighting: 8hours 18W x2
Co2: 3bps
Soil: Ada Amazonia
Adding in around 1-2ml of iron daily.
Up aqua flora nutriment 5ml weekly

Yeah, its normal... they are stem plants and the aerial roots help them get nutrients from the water column too.
These plants can actually be kept without soil, just tied to rocks or wood.
Thank you chazrt and UA. Is my lighting sufficient for HC? Cos when I extend my lighting period to 9-10hours my flame moss on my branch starts turning black.

It depends on the size of your tank and the distance of the light from the plants, but with Co2 injection its generally much easier to grow HC, the amount of light will mainly determine its growth rate (and consequently the Co2 and nutrient uptake).Originally Posted by eiontay
For your flame moss turning black, if its new it could be adapting to the tank, or if its too close to the light it could be getting over-exposed to too much light.
Tank is 45x30x30cm tank. And the HC is roughly 30cm away from the light. Flame moss 10cm

That amount of lights should be fine for HC in those tank dimensions, just make sure there is sufficient circulation to get ample Co2 and nutrients to the HC, and ensure that they are not shaded from the light.
As for the flame moss, it might just need some time to adapt to the closer light proximity/higher light intensity that it is receiving, moss tend to die back when conditions change and then recover again once they adapt to the new conditions.
What would be the possible reasons of staurogyne melting? Tank temperature is about 28 degrees.

You will need to provide more information for anyone to be able to make an "educated" hypothesis.
If they were newly planted, it could just be due to the emersed form transiting to submersed conditions, so some melting of the weaker/damaged leaves may occur. Could also be due to deficiencies in certain nutrients too.
Temperature isn't much of an issue with staurogyne repens, i currently have a batch in a low-tech outdoor tank with inert sand substrate running at 32-33°C and they are still growing well.
Thanks Urban Aquaria! Yes, mine is newly planted on ADA soil. It's puzzling that my HC survives and spreads but not the staurogyne. Will overdosing of certain nutrients cause it to die off? I dose bright lights, potassium, iron and flourish once a week. Tried twice.. certainly stressed! ;p

If you are using new ADA aquasoil along with dosing potassium + trace/micro ferts, then nutrients shouldn't be an issue (since your HC is doing fine too)... those ferts usually wouldn't affect plants negatively even at higher dosages.
I guess it looks like the staurogyne repens could just somehow be weak specimens, though they are usually very hardy plants.
Btw, do you have a photo of the staurogyne repens in your tank? Just to confirm its the same species.
This was home-grown and had thrived very well for a few months. But filter was spoilt while I was overseas for a week and water was very bad. The repens didn't survive the reddish brown algae (or whatever it was) outbreak. 2nd time I bought from farm and they only lasted for a few weeks.

I guess your tank conditions were suitable for that plant since it was previously doing well for a few months... so just have to tweak your current parameters to see how to return it back to those conditions.
Do you have Co2 injection in the tank? And how long has the ADA aquasoil been used for so far?
Is this the plant that can be re-planted by snipping off the stems and replanting them in the soil?

Literally all plants can be replanted by snipping off the stems lol.

Yes, its a stem plant so its propogated by cutting the stems into shorter sections of a few leaf nodes each, remove the bottom leaves, then replant them.
Yes, there is co2 and the ADA soil has been used together with substrate additives since tank setup in Feb this year..

Since there is Co2 injection and the ADA aquasoil is still relatively new, looks like you'll just have to get another batch of healthy staurogyne repens to try again, hopefully they'll establish and grow well this time around.
Ok Urban Aquaria, thanks for your encouragement!
