Open catfish caves

Continuously open clay caves

Suitable for witch catfish or as a hiding place for catfish, invertebrates and axolotl

The size of the animals determines the size of cave required.

Rough rule of thumb: diameter = width of the catfish body + one pectoral fin length = 1-1.5 times the body length of the male catfish

As a rule, narrower caves are preferred.
In the case of simple tubes, the diameter always refers to the inside dimension!
