My last (famous last words) shipment of rock came in, 70lbs keys and 10lbs coral. Now I have 120lbs of rock in my aquarium. I really like a lot of crannys and pathways so I have it scaped like a maze. My favorite part is the big cavern under the branch rock, will take better pics of that for my gallery. My fav piece of coral rock has a few xmas tree worms, I love those!
