I have literally only cleaned out the tank recently so next time I will consider using paper towells.
I cannot find a good UK alternative to pedialyte. The UK version is Dioralyte but is only available in blackcurrent flavoured dissolvable sachets so no good

Any other suggestion what may work for this?
He has not touched food for a couple of days again and still remains sitting on the floor constantly a very dark colour.
On a more positive note, I picked him up last night to inspect his belly and check for redness etc, and he jumped really far from my hands back in the tank to near the top which must be a good sign!
He did however struggle to hold on for some reason and after about 20 seconds fell from near the top luckily into the water bowl to break his fall. He seemed ok from the fall but concerned that he didn't have the strength maybe to cling on
