I want to say it's Christmas moss, but not 100% on that one.You have so many beautiful fish! I had no idea they were the size of neons. And wow, the colour on the the highlighter fish (kubatai? Is that right?) even more tempted by those now.
What moss is that you're using with the fry? Is it Christmas moss? I've only had java moss, but this looks quite nice
I bought a cup of "assorted moss" where it was supposed to be a mix of java moss, Christmas moss, and weeping moss. But definitely not the java moss, I actually got a tiny bit of that and its not flourishing as well as this moss.
A stray piece of java is in this mix though in the parent tank lol
