It was in a tank with low light and it wasn't rooted in the substrate, just floating around. Also the tank was chocca with Hydrophila difformis which was cutting out a lot of the light, which probably explains why it isn't as colourful as it should be. However it was noticibly red/pink compared to normal Cabomba which is why it caught my eye.
With all the ferts that Jennifer doses and the good lighting and CO2 injection it should come right
