I love cryptocorynes but there are thousands. They can look very different depending on your growing conditions. I belong to a plant club & they need a flower from a crypt grown emersed (leaves out of the water) to even begin an ID.
Your first plant is different than any I've grown (or tried to grow). Short wide leaves with some reddish leaves, I have no guesses. What was it called when you got it? & the 2nd plant? What was it named? Common names are not always very accurate but can be a hint...
Have you looked for a cryptocoryne specific site? I know there are some, but I also see English may not be you first language? I will look for a better site to help you.
