The two larger ones do appear to look skinnier today. They still gather around the one place behind the large sword plant.
There is no moss in this tank. There is ground cover in the foreground (dwarf hair grass) but that is about 8 inches forward of the sword plant.
Current observations are that they spend most of their time now in the front of the tank, like they used to do, but still occasionally go back to the same point under the sword.
Thanks for the quick reply post, Laura.
