Have Questions About Cold Water Fish for Sale?
We have answers. Get quick help for common questions.
1. What are coldwater fish?
Coldwater fish are species that live happily at room temperature without a heater, such as goldfish, white cloud mountain minnows and some loaches.
3. What size tank do goldfish need?
Goldfish grow larger and produce more waste than many people expect. Fancy goldfish need at least 75 litres for the first fish, plus space for each extra fish, and good filtration.
5. How are live fish delivered?
Fish are packed in oxygenated bags inside insulated boxes and sent by a dedicated livestock delivery service. Acclimate them slowly on arrival.
2. Do coldwater fish need a heater?
Most don't, as they're happy at normal room temperature. Keep the tank away from radiators and direct sunlight to avoid big temperature swings.
4. Can coldwater fish live with tropical fish?
It's best not to mix them, as they need different temperatures. A few species, such as white cloud mountain minnows, can tolerate both.
6. Can fancy goldfish go in a pond?
They are best kept indoors. Their rounded bodies and long fins make them slow swimmers, and they struggle in cold winters and with pond predators.
Coldwater Fish for Sale
Coldwater aquariums do not need a heater, and they can be just as colourful and interesting as a tropical tank. Our coldwater fish range includes fancy goldfish, common goldfish and other species that are happy at room temperature in most UK homes.
Goldfish are the classic coldwater fish, but they grow much larger than many people expect and produce a lot of waste. Fancy goldfish need a spacious tank with strong filtration, and single-tail goldfish such as comets are best kept in large aquariums or ponds. If you want smaller coldwater fish, look at our temperate fish, such as White Cloud Mountain minnows, which suit cooler tanks.
Always plan around the adult size of your fish. Choose a properly sized goldfish tank, run a filter rated well above the tank volume and fill it with quality freshwater filter media. Treat new water with dechlorinator, check ammonia and nitrite with freshwater test kits and feed a specialist goldfish food in small amounts. Regular water changes and gravel cleaning keep water quality high.
Charterhouse Aquatics keeps a changing selection of coldwater fish, and our team can help you choose fish that suit your tank size.
