Yes I’m adding prime with every WC. Temp avg is ~77.7f. I’ll order some more substrate since he has light color sand that is slowly decreasing over the years. Good idea about the fake plants! I’ll see if Amazon has some decent options. Thinking about buying/ feeding him some live mealworms to see if appetite back at all.
Flukers reptile vines are great. Amazon has them. If you don't have a background add one. It reduces stress and aids sick fish. Add a couple floating fake lily pads too. Make the tank a cozy bed!
