Strange new feathery tendrils on plants

[kw1964]

Hi there, I am looking after my son's 100L tank whilst he is at uni. I have noticed over the past few days that his plants (I tink they may be java fern but don't know for sure) have started sprouting long feathery filaments from the top of the leaves. Is this normal? I have watched a few YT videos saying new plants can grow from leaves but these filaments don't look like new plants. I have attached a couple of photos. Details of tank (as far as I know) follow;

100L tank
Fish - one Oranda, nothing else.
water change each week about 20%
I add liquid carbon and plant food each week. I also use the Evolution Aqua Pure Aquarium and Waste Remover balls
Two filters, a HOB-500 from AllPondSolutions and an external filter, plus an air stone.

Thanks in advance.

Looks like green thread algae. Amano shrimp will eat it. 🙂

Hi all,
Welcome to UKAPS

Looks like green thread algae.

Could be, but I think they may be filamentous diatoms (Synedra (Fragilaria) sp.).

If @kw1964 runs them <"between their fingers">, you should be able to tell, <"very slightly gritty = diatoms">.

Many thanks Darrel - I will take a look this evening. If it IS diatoms, what is the recommended way to get rid? I have done nothing different to the tank / cleaning regime etc. for months no not sure why they should appear now.

Hi Darrel. I touiched some of them and they didn't seem at all gritty, just slimy. I also did a water test and no ammonia or nitrite, Nitrate was between 0 and 0.25.
