HI all! I was directed her because the question I have does not suit the other post. I was wondering if any of you have experience will fish terraces or something like that. My stock plan for the 10 gallon is 1 Mexican Dwarf Crayfish, 10 Yellow Shrimp, 2 Mystery Snails, and 6 Malaysian Trumpet Snails. I am also putting driftwood, plants, and something that looks like this in the tank. Do I need the terrace or am I fine?
