[Fresh water aquaria and veterinary practice. 2. Studies of proper raising of ornamental fish].

The environmental conditions in 103 fresh-water aquaria were examined and the results compared to the standards as described in part 1 of this publication. The aim was to assess whether the care of aquarium fish was adequate in regard to management and the legal requirements of animal welfare. Disclosed faults are discussed and recommendations for their elimination and avoidance are suggested.
