Bostrychus zonatus is a sleeper goby and becomes about 15 cm long. They are predatory fish, which should therefore only be kept together with species that have at least half the body length of the gobies, larger is safer.
The beautiful animal is widespread in fresh and brackish water in New Guinea and northern Australia. It is therefore a good idea to keep for it together with rainbowfish from this region.
The colouring can change very quickly depending on the mood, excited animals become very rich in contrast.
These animals demand hard water, in any case the pH-value should be above 8 if possible. Soft soil, many hiding places and a light addition of salt (the latter is not absolutely necessary) increase the well-being of the quarrelsome fish.
For our customers: the fish have code 396503 on our stocklist. Please note that we only supply wholesalers.
