Have Questions About Live Fish?

We have answers. Get quick help with buying and caring for live aquarium fish.

1. How are live fish delivered?
Live fish are sent with APC's specialist livestock delivery service, which runs Wednesday to Friday. Delivery costs £24.95 on livestock orders up to £200 and is free when your order includes £200 or more of livestock. Please make sure someone is home to take the delivery.
3. How do I add new fish to my aquarium?
Float the sealed bag in your tank for 15 to 20 minutes to match the temperature. Then add small amounts of tank water to the bag over the next 20 to 30 minutes before netting the fish into the aquarium. Keep the lights off for the rest of the day.
5. Do I need to cycle my aquarium before adding fish?
Yes. A new tank needs 4 to 6 weeks for filter bacteria to build up and remove ammonia and nitrite. Test the water and add fish only once both read zero.
2. What if a fish arrives dead or unwell?
Contact our customer service team as soon as possible on the day of delivery, with a photo of the fish still in its bag, and we will help put it right.
4. How many fish can I keep in my tank?
It depends on the adult size of the fish, your filter and how often you change the water. A cautious starting point is about 1cm of adult fish per 2 litres, added a few fish at a time.
6. Which fish are best for beginners?
Hardy community fish such as platies, guppies, Corydoras, zebra danios and many tetras are good first choices. For an unheated tank, cold water fish and goldfish are a better fit.

Good to know

Why are some points pending?

Purchase points have an approval period before they become available. Your balance shows available points separately from pending points.

How long do my points last?

When points expiry applies, your balance stays valid for 365 days from qualifying rewards activity. Earning eligible rewards, redeeming points or a balance adjustment renews that window. Simply visiting the shop does not renew it.

Can I use points with my stamp reward?

Yes. Add your 10% stamp reward code at checkout and switch on your points. Your final saving depends on the eligible product total and any other discount restrictions.

What happens if I return something?

Earned points are adjusted for returns. Points used on refunded products are restored proportionally. If a refund takes a qualifying order below £250, its stamp is removed.
