Rotala Rotundifolia Orange Juice

I purchase the Rotala Rotundfioloa Orange but a month later the plants turn red. I am not sure the plants delivered corect type or my environment. Tank has CO2 injection, Twinstar S ver IV light with 8hrs durration.

3 out of 4 plants arrived healthy. The rose sword came melted and dead.

Nice amount of very attractive plant. Little to no roots.
