Not sure if anyone's even reading this thread, but I'm going to update just in case
I woke up this morning to find Speedy halfway up on the back glass -- positive confirmation that he is indeed still alive! His little suction-cup feet were out all over the place, he was definitely hanging on tight and looking for other footholds. He used to be white with purple-tipped spines, now he looks 'grubby', I don't know how else to describe it. He's lost a lot of spines, and seems darker in colour, but definitely alive. I hope to be able to update in a while and say he's fully recovered
