Three spined stickleback

Description: The three spined stickleback (Gasterosteus aculeatus) is a fish native to the UK. It is found in both freshwater and around the coast. A very interesting species and subject to much scientific study for a variety of reasons. It displays anti-predatory behavior and has nest building habits at breeding time. Easy to keep in ponds and aquariums and easy to breed. Our sticklebacks are produced on site by us. Variations in size between 2-5cm according to season.

Maximum Size: Upto 3″ but on average 1-2″ when mature.

Environment: The Stickleback is well suited to smaller garden ponds but benefits from well filtered pond with vegetation. It is a shoal fish so benefits from 3 or more of the same species to fulfill it’s shoaling desire. They do breed well in garden ponds, most notably those that have prolific weed growth and are well oxygenated. Sticklebacks are quite tolerable of poor and polluted conditions and are often the first species to return after major pollution incidents in waterways.

Water Conditions: Sticklebacks require a pH range of 7-8.5, Ammonia and Nitrite to be virtually 0ppm and dissolved oxygen saturation to remain above 8ppm. Sticklebacks are not noted to be sensitive to pond treatments but please seek professional advice before treating your pond.

As with any pet, please fully research for yourself to ensure that you can accommodate a fish of this type in your home.
