Starfish seperating arms

So it's now October and atleast some of the arms are still alive and moving. The part of the starfish that had 2 arms is starting to regrow 3 more from the end. Hard to tell from the angle but will post more pictures when I can get a better shot. As for the other 3 individual arms atleast one of them is still going. I only ever seem to see one at a time and they move around a lot so not sure if it's the same one or not. The ends are healed over but nothing is growing yet. This all started back in February though so by now I have to assume it's eating something.

National Geographic here I come!

Growing 4 tiny arms

what does it look like now?

I have seen sea stars lose limbs that continue to freely move afterwards, but typically only for a week or two before melting away. I’ve also heard or a limb with very little to no oral disc attached reforming a new mouth, but it seems to be rare. This takes it to a whole new level of my understanding.

It’s also important to note this is a fairly uncommon species (and genus for that matter) in the hobby and if it were a more common genus(Linkia and Fromia) I would expect the outcome to be melting quickly.
This comment is kinda rambling, sorry. This is rad.

My red linckia lost all its 7 arms over the course of a month and now only has its central disk left. It is still alive and hiding in the rock work.

Sorry, I don’t have much info on starfish regeneration…..

So the latest update. The 4 tiny arms growing is still going on. They are growing very slowly. This has almost been a year now but as you can see in the last picture there are clearly 4 distinct new arms. It often disappears for a few weeks at a time. I assume behind the rocks but always reappears eventually.

I’m my extensive further research google seems to say they generally only regrow a singular lost arm or split down the middle to replicate but there is also always a disclaimer about how there are so many different types of starfish and many have not been extensively studied. I have also found very little about this specific type seems to be known since they are very rare in the hobby.

I did find a new Lfs a little farther away and I was asking the guy about it. He said when he had one of them a while back it split apart into 5 separate arms seemingly for no reason too. All the arms on his died after several months . I’m thinking since the 2 arms on mine stayed connected by a thread then there was enough of a central disk left to regrow the arms.

Can you take a picture of it when it comes out, and show it to me?
