We have an extensive range of outdoor pond fish for sale, including Japanese Koi Carp, Goldfish, Australian Native fish and more. People tend to think that you cannot have much variety in a garden pond or water feature, but we have many different types of pond fish available, most of which will happily cohabitate, creating a more natural ecosystem within your pond. All of our cold water pond fish are suitable for the water temperature range of an outdoor garden pond without any form of heating.
We stock a huge range of tropical aquarium fish, including cichlids, community fish, monster fish, live bearers, natives, and a dedicated bay of various rainbow fish species.

Australian Bass
Bass are great for ponds and dams that have large fish in them. Do not mix them with small fish, because they will happily devour anything that will fit in their mouths!

Murray Cod are a large native fish that can grow up to 180cm in the wild, but will rarely exceed 65cm in a pond. So only mix with larger fish such as koi and other large natives. A predator by nature, murray cod love a place to hide surprise their prey, such as overhanging driftwood or rocks. Can eat sinking pellets and live feeder fish, insects etc.
Tandanus Catfish are great for larger ponds of at least 600 litres. They have the potential to get big, so will mix well with koi and other larger native fish. Not a fussy eater, they will eat pellets, especially sinking pellets. An interesting addition to any large pond.

A small schooling fish that comes in a variety of nice patterns/colours, we stock these in zebra (shown), leopard and golden strains as they are able to live outside in cold weather. Frog friendly and mosquito eating.
Found in the rice paddies in Japan, these little fish grow to a maximum of 2.5cm. They are frog friendly and peaceful, mixing well with other fish of a similar size to them. Very popular in planted patio ponds.
Nice little schooling fish that will reach a maximum size of around 4.5cm. Males are bright red and females a more copper tone, but they are still pretty. A great way to add colour and movement to a pond of a minimum size of 200 litres.
A best seller! Great little fish from the clear mountain streams in China. These hardy little guys will reach a maximum of around 2.5cm and are frog friendly! Will breed in a well-planted pond of a minimum size of around 150 litres. Like all fish will eat mosquito larvae.
Also known as Algae eaters. That’s all they do. Eat algae! Well, they also have a bit of character, chasing other tank mates occasionally, they think they own the place! They are harmless, though. In most ponds, they will get to a size of about 12cm, but I have seen some reach up to 30cm! Give them some space so they do not think that the whole pond is theirs. Min pond size 300 litres.
A small native shrimp species perfect for adding some biodiversity to your pond. Best kept with small fish that will not bother them such as minnows and blue eyes.
Will feed off of algae within the pond and breed in well-planted areas.
A great additon to any pond, dam or fish tank, mussels are filter feeders so will naturally help to keep your water clean.
Not much to them other than this but excellent to provide some extra filtration and biodiversity to your pond.
Axolotls are a 'paedomorphic' species of slamander meaning they remain in their larval state into adulthood. Native to only one river in Mexico and critically endangered in the wild we have stable captive populations in Australia.
These freshwater amphibians like cold water so do just fine in the outdoor pond. All of our axolotls are trained to eat sinking fish pellets (meaning you can forgo the live and frozen worms)
A staple in tropical aquariums, Neon tetras are small, colourful freshwater fish with amazing schooling behaviours. They’re hardy and social, making them a popular choice for both beginner and experienced hobbyists.
They're a social species, so we recommend keeping a minimum of 6.
Read more about neon tetras HERE
Cardinal tetras are very similar in appearance and behaviour to the popular neon tetra. They are often preferred because, unlike neons, their characteristic red marking extends across their whole body, making them more satisfyingly colourful.
They are also a social schooling species local to the Amazon Basin in South America.
Tiger barbs are energetic, striped freshwater fish from Southeast Asia. Their wild colouration is orange with dark black stripes. We also stock their 'golden' and 'moss green' varieties.
They bring a lively, dynamic presence to any aquarium, but can be quite aggressive in community tanks, especially if kept with more passive or smaller fish. To keep them happy and harmonious, they’re best paired with other robust species or kept in a larger, well-planted tank where their active nature can be comfortably accommodated.
Guppies are a great beginner fish, though even experienced fish keepers often find themselves hooked on their easy going and colourful nature.
They’re super easy to care for and come in a huge range of colours and patterns. Watch out if keeping males and females together, though, unless you want to coparent hundreds of babies 😉
The Black Ghost Knife Fish is native to the Amazon basin of South America. If given enough space, they can reach lengths of up to 60cm!
They are carnivorous, so like a high-protein diet. They are super cool fish in lots of ways. Moving around with one long fin along the bottom of their body, they are related to electric eels, using their (very weak) electricity to locate food in murky water. They are peaceful community fish but may eat tank mates that are smaller than 4cm...
Phantom glass catfish are another super unqieu and beautiful species. Native to South East Asia they are a peaceful community fish that do great in tropical tanks.
Their bodies are completely see-through, allowing you to see their skeleton and organs. With a microscope, you can see their heart beating!
