R. woodsi has been kept in the aquarium. A timid fish species, they should not be kept with boisterous tankmates. Active at night, they will hide throughout the day. Though they will eventually recognize prepared foods, it is best to acclimate these fish on frozen brine shrimp. They have an affinity for wood, which should be included as part of the aquarium furniture. References
