Anubias Health

I got some anubias last week and planted them in my 30 gallon tank(by attaching to a rock and driftwood)
Now my biggest one lost a leaf so I checked rhizome and notice parts of it is brown here are some picks:




I know this means trouble but what should I do I used cotton string not plastic so it won’t cut and harm rhizomes also it almost loose I tied my another anubias like this and now it is losing some of its new leafs but older ones are okay
Should I risk the plants floating and cut some of those strings or they just getting use to their new environment??
Also this is my anubias white:


Is it healthy or not??

 

You might want to use a clean razor to slice off the brown end of the first Anubias. You don't want the rot spreading further! Though it may just be that the end was injured somehow because the rest looks healthy.

I don't like the brown patches on your white one, that doesn't look healthy at all. Where did you get them?

 

So I would also be concerned about the anubias white... assuming it's a pinto??? Shouldn't look like that. I believe Mcasella might grow this variety and can help more...

One possibility is that both have been grown emersed (out of water) before they came to you and are adjusting to growing submerged... however for the white one adjustment doesn't look like that...

 

Thanks for replies
Those brown markings on my white anubias are kinda like they are molting also only 3 of the leafs have these problem others look okay also I can see 2 small shoots coming out should I cut the brown leaves or wait??

 

I would trim the brown rhizome and leaves off, this prevents the plants from wasting energy trying to save the leaves.
The white does not look healthy, at least those leaves dont, I would trim those off and wait for new growth.
Anubias are one of the easier to transition ones as long as they aren't buried or brand new plants (from seed that is, sister cuttings normally don't have issue).

 

Okay so tomorrow I will start cutting if anything happens I will ask

 

Okay so I'm done with cutting:


And for my white one:




I don’t know what was that brown or gray thing was but I think it was some sort Fungus some of my healthy leafs were turning like them from the part that they had contact with infected ones so I cut them too
Also I move it to somewhere with better view for better observations

 

If you need to you can take the white out and give it a methylene blue bath to prevent the fungus from spreading, if you think there might be a chance you missed some on the leaves or some might be somewhere else on it.
They both look better with the dying leaves removed.

 

Since I had methylene blue(from an old titration test) I gave my white and my king kong anubias a bath and then washed it also I removed rotting plants from King Kong and tied it much more gently to his rock
