Safe for all varieties of corals and their allies, including colonial and solitary polyps.
Experienced hobbyists are well aware of the delicate nature of the soft tissue that constitutes the living coral polyp, particularly in the case of stony corals. Inspection of a bare stony coral skeleton often reveals a very convoluted and sharp structure; when coral tissue is inadvertently pressed against such a structure, the resulting local tissue damage can create an entry way for infection and/or infestation by organisms that would otherwise be combated by the coral’s immune system. Physical damage to coral tissue is not an uncommon event during shipping and/or handling, and is an unavoidable result of fragmenting when the cutting site is not bare skeleton (again, in the case of a stony coral; cutting soft corals and polyps will always result in tissue damage). A colony or individual may also experience stress as a matter of changing chemical or physical conditions in the aquarium, often leading to weakening of the immune system, with the afore-mentioned infection/infestation as a possible result.
