aquavitro® premium surgical stainless steel Straight Forceps are designed for use in both freshwater and marine aquariums. These are ideal for planting and maintaining aquatic plants, particularly plants with thick or broad stems. They are also preferable when planting in gravel substrate (as opposed to sand). In marine and reef systems these forceps work well in placing or retrieving coral frags or colonies. These are often used in the general aquascaping of any aquarium.
