I learned that grass seeds grow more then mustered seeds our terrarium has isopods crickets one of our crickets died because it didn't have enough food to live .So in our aquarium we have two fish and to snails our fish go up alot our snails don't move so much but the little one likes to move in the gravel alot and it moves around the container.I like doing this because It helps use when we are In 5gr next year.
