I have some star grass that when I first got was bright bright red in my tank. It stayed red and grew, but got a little to big, so I trimmed it back. Since then it has been only green with some recent tinges of red. I first planted it with root tabs, but I was told it is a water column feeder not a heavy root feeder, so haven't used any lately. It is in a 75 gallon tank under a 4 x 55 ahsupply kit. With CO2 injected. It is growing good, just not turning red.
I have some other red plants that are turning colors, but the star grass just isn't.
