That is so kind, but I have that particular one. It makes sense you got it from another hobbyist, and even then it's not too common. Mine started as TC and yeah, pretty slow growing even compared to other crypts IME. It was one of three crypt species in a nano tank
I just took down, and a single original plant had made about a dozen runners in four years, which is way fewer than I got from the other two. It's very pretty though and the leaves are so distinct you can easily pick them out in a sea of other crypts. Definitely worth having, glad you were able to track it down.
