I recently got into terrariums and have tried to make two now..

I have been trying to get into building aquatic terrariums but am slowly learning the setups I’ve made are not great. None of the plants are rooted.. I just gathered various plants from the area I got the other materials from(a flooded park on the right and a pond on the left) and threw them into the jars. I have since then purchased some Christmas moss that I got onto some rocks and replaced into the terrariums but am not seeing much life if any. Only some tiny red worms in the pond jar that are burrowing in the white film building atop of the water. Any tips would be greatly appreciated ❤️
