Thanks for your comment. We take the welfare and comfort of our animals very seriously, and undertook copious research on the biology and behaviour of Queensland Lungfish before designing the enclosure and determining how to care for this species. In the wild, lungfish are adapted to live in stagnant water and have poor eyesight, remaining stationary for long periods (particularly during the day), and feeding on plants and aquatic animals at night.
Queensland Lungfish have relatively small home ranges and their activity is usually restricted to courtship behaviour and instream flow events in their natural habitat. Otherwise they are reported to be slow-moving and sluggish in the wild. Researchers have found that Queensland Lungfish is a ‘sedentary species, reluctant to move even during times of flood’.
The housing for our lungfish is in excess of the recommended dimensions for this species according to Australian regulations. Many animal species require smaller enclosures than might seem natural, to help with their comfort and security. Animal species that live in burrows or under logs, or shelter in cavities such as tree hollows and rock crevices, or in restricted aquatic habitats, become extremely uncomfortable and stressed in larger spaces, particularly when kept in these spaces for long periods of time. As animal keepers and enclosure designers, we have to avoid the anthropomorphic tendency to project our needs on those of our animals, particularly regarding food quantities and housing size.
But we take your comments on board and thank you for your concerns.
