Hey I'm glad that stuff got there in good shape. Sometimes shipping to California can be kind of slow for some reason(???).
Nice work planting that stuff up. That looks perfect. Those plants were both on the small side, but just give them some light and they should grow for you. You might see the Lagenandra melt back some, but it will grow back. I have some here that I started a couple of months ago in planters and they are starting to fill out nicely. Now that you have the Lagenandra in there it will be good to keep the lid on the tank to keep humidity up.
