The TLF Little Feet Frag Bases from Two Little Fishies , weighing 2 kgs, offer stability and versatility for corals and frags. Crafted from flat limestone, these bases provide a secure foundation for large corals or frags, with a bottom surface ideal for positioning within aquariums or coral culture raceways. Their design allows for easy placement anywhere in the tank or even burial in sand. The flat upper surface features holes and depressions to assist in positioning smaller frags, while also facilitating the attachment of larger corals using epoxy or cyanoacrylate adhesives.
