Thanks! I think it looks like a hot mess. But after a few months (or a few million months) of Crypt growth, it should look acceptable. Once the Christmas Moss grows in, the tank will look solid.
Thought about doing a carpeting plant but don't want to use CO2 or ferts. In my experience, it takes Marsilea about a year to really spread well without both.
A note about the Crypts I've already planted: the ones in front are C. parva. The ones in back are allegedly C. parva but are giant bit comparison - and they've been submerged in another tank for about sixteen months. Figured they'd look decent behind the wood when viewed from above. Didn't want anything too tall, as this is going to be a shrimp tank.
