To improve maintenance conditions for their facility's Xenopus laevis colony, White-James et al. replaced their cumbersome housing setup with a rack system that was originally used for zebrafish. The rack's self-contained water circulation and filtration system eliminates the need to wash tanks by hand, and a temperature-control mechanism helps ensure optimal environmental conditions. The new housing solution also saves space, allowing many more aquatic species to be housed in a single room. See

In an effort to contribute to the development of standard protocols for Xenopus laevis husbandry, Wassersug et al. explored the effects of feeding schedule and the availability of cover on frogs' post-metamorphic growth and behavior. They fed frogs either daily or episodically, and gave them access to varying numbers of shelters. Feeding frogs daily helped them grow larger, and shelter did not affect their growth. See
