Nice, just saw that we are going for a similar setup/stock. As the others said, some full shots and parameters would be nice. Mine, too are still not in the best of shapes and arrived in similar condition as yours. They're getting better every day though, and I've set up their qt tank a bit homely with wood, floating plants, tannins and cattappa leaves, similar to what their more spacious permanent setup will be. Seems to work, they seem to feel right at home.
Best of luck,
Tobi
