Thanks Gina, good call. I went ahead and repotted this morning. Bottom of the old pot was very "mucky" indeed.
Roots still look OK, I think it has a chance.
I repotted into better soil and a couple of rehab pots. Decided to split off the smaller pieces into a smaller pot. If they grow, I'll eventually put them all back together, but that might be awhile.
Unpotted and rinsed off:
New pots and soil:
Now to give it time and see how it does.
