I thought astreas would be safe...good god. He even fragged my star polyps for me...I had to move some rocks to help him put his cave together and one passed by the opening of his little cave...he punched it and it broke in half...a sound came out of my mouth that I had never heard before as I quickly removed my hands from the water...he's STRONG...seriously, Im nervous about the integrity of the aquarium. Im really dissatisfied with the arrangement of the corals but it'll just have to do for now. Pics later on tonight.
