Looks good, you obviously are super into your planted setups. I am too scared to try dirt, I don't know enough about everything yet.
About the crypts; I got a crypt wendii red that I put in my 10 gallon. It totally melted within about 2 weeks, but with patience it has come back to almost the size it was when I first got it. I'm not sure I would buy more in the future, but it has been cool to watch it appear to die, then come back full-force. There are even some little side shoots that I didn't see before, and that's without any nutrients in the substrate, just tahitian black sand
