Crypts (and other plants) will sometimes change color depending on light intensity; also change leaf shape.
I have had green crypts have wide brown leaves in lower light and skinny green leaves in higher light. Nothing to be conserned about.
Hey thanks, I figured as much that my plant was just adjusting to the tank. But would you say that I'm running too low of lights then? I have a 29 gallon and the lights are aquaticlife t5's with 2x24 watt bulbs. I would say that my light is about 20 inches above the substrate
