Formisquarium Outworld (XL)
This large outworld is designed with the Formisquarium XL in mind. Dimensions are 20L x 10W x 10H (cm), and the two ports are drilled to match the nest entrances on the Formisquarium XL. It has a sand-coated, well-decorated ultracal base, that allows for plenty of space for feeders and general maintainence. It is easy to clean, and allows for plenty of foraging space for a medium to large sized colony.
The lid fits tightly to prevent escapes, and the two ventilation holes are sealed with a stainless steel mesh to allow for ventilation while still being escape-proof.
