Cohabitation
Single keeping. Little is known about the species' own social behaviour; the genus is regarded as solitary, and males are aggressive toward each other. Never keep two males together. Pairs (one male, one female) are possible if each animal has its own warm and retreat spots and is fed separately when sizes differ.

Notes

A decidedly cold-house species: room temperature in summer is already too warm, and above 26 °C things get critical. Acquire it only with unbroken proof of origin — legal animals are rare.
