aquavitro® premium surgical stainless steel Curved Shears are designed for use in both freshwater and marine aquariums. These are ideal for the regular maintenance of aquatic plants, particularly when trimming leaves and stems closer to the aquarium bed where the steep angle is mitigated by the curve of the shears. In marine and reef aquaria these work very well in trimming soft coral with ease to maintain shape, spacing or to produce frags.
