An experiment was done in which two ajolotes xochimilvo, one black ajplote the other albino, were cut in half laterally and sewn together. They are especially easy to breed compared to other salamanders in their family, which are almost never captive-bred due to the demands of terrestrial life.

Substrates are another important consideration for captive axolotls, as axolotls like other amphibians and reptiles tend to ingest bedding material together with food [29] and are commonly prone to gastrointestinal obstruction and foreign body ingestion.
