Cholla or also Vuka woods are the skeletons of columnar cacti (Cylindropuntia bigelovii). They offer numerous hiding places for young fish & prawns. They are ideal for shrimps because they can withdraw into the cholla tubes with pieces of food and eat undisturbed.
It attracts biofilm for surface rasping/foraging fish, shrimp and snails. Aquarists also use cholla wood as a decorative aquarium driftwood or aquatic plant base.
