Up Aqua's Pleco Spawning Cave is specially designed for the existence of pleco. It is open at one end and closed at the other, allowing a dark area in the tank for the plecos to spawn. The width of this cave is slightly less at the top than it is at the bottom, adding visual interest to the piece.
The cave provides both shelter and added biological media. The ceramic material is inert and will not alter water parameters. It can also be used as a functional decoration in your aquarium.
