aquavitro® Seachem premium surgical stainless steel curved tweezers are designed for use in freshwater and marine aquariums. These are ideal for planting and maintaining aquatic plants, especially plants with thick or wide stems. They are also preferred when planting in gravel substrate (as opposed to sand) and when planting in corners or around rocks and driftwood. In sea and reef systems, these tongs work well when placing or retrieving coral fragments or colonies. These are often used in the general aquascaping of each aquarium.
