First is "Self Fragging" the correct terminology? Secondly i am very new to this whole hobby and if you view our build thread you will see this a class tank for a special education biology class. what does this tell us if anything? ( Tank healthy? Coral trying to survive or stressed? Natural growth? ) is there anything We should do? My concern is this piece breaking off at night or over a weekend and getting sucked into power head, should I cut it off there and secure it to a rock?
