How does Fish Cave Aquatics ship live fish?

Fish Cave Aquatics inspects all livestock before dispatch, packs it in insulated containers and sends it with trusted couriers to reduce stress and risk in transit. The shop describes deliveries of dead fish or coral as rare and covers them with a dead-on-arrival policy. You should inspect the order immediately on delivery, because the time limit for reporting a problem starts when you sign for the parcel.

What does the Fish Cave Aquatics dead-on-arrival policy cover?

The Fish Cave Aquatics policy covers only livestock that is found dead on arrival. Fish that show signs of distress or die after being placed in your aquarium are not covered. The shop accepts no liability for unsuitable tank conditions, improper acclimatisation or mishandling after delivery. Claims made after the two-hour window, without the required evidence or after the packaging has been opened or tampered with are void.

What happens after a Fish Cave Aquatics DOA claim is approved?

Once Fish Cave Aquatics has reviewed and confirmed the claim, you can choose between a refund for the value of the affected livestock and a store credit towards a future order. The shipping fees are not refunded in either case. If you pick store credit, check whether a voucher code can be used alongside it on your next order.

How long do I have to return dry goods to Fish Cave Aquatics?

Fish Cave Aquatics states a 7-day return option for dry goods, such as equipment, decorations and water treatments. Livestock falls outside this and is handled only under the dead-on-arrival policy. Because shipping fees are non-refundable under the shipping policy, it pays to check sizes and compatibility, for example of a heater or filter, before you order.

Does Fish Cave Aquatics have weekly deals?

Yes, Fish Cave Aquatics runs a «This weeks Top Deals» section and a «Top Aquarium Deals» section with a countdown in days, hours, minutes and seconds. Recent weekly deals featured 15kg Betta Choice Black Gravel, the API Aquarium Start Up Pack and the Fluval 407 Canister Filter. Items already reduced in a deal may be excluded from a voucher code, so compare both in your basket.

How can I contact Fish Cave Aquatics?

Fish Cave Aquatics provides a contact form on its website that asks for your name, email, phone number and message. An email address published for the company is accounts@thefishcave.co.uk. For a dead-on-arrival claim, contact the shop within two hours of signing for the parcel and keep the packaging unopened as evidence.

Fish Cave Aquatics: tropical fish and aquarium supplies delivered to your door

Fish Cave Aquatics Ltd is an aquatics shop for fishkeepers who want to buy livestock and equipment in one place. It sets out to bring tropical fish from all over the world direct to your doorstep, and it stocks the tanks, filters, heaters and water treatments a home aquarium needs. With a voucher code from save-up.co.uk, your order on fishcaveaquatics.co.uk can cost less.

A range built around the home aquarium

The shop groups its products by what a tank needs to run. Alongside complete aquariums such as the Tetra Starter 105 Litre LED Fish Tank and the Ciano Aqua 60 LED Aquarium 58L, available in white or with a black stand, you find a section of everyday essentials. Water care comes mainly from API, with Accu-Clear and Ammo Lock, the latter in three bottle sizes.

  • Aquarium air pumps and air supply: Betta Airline Tubing, SuperFish Air Sponge Filter, Fluval and Marina valves
  • Aquarium heaters and filters, including the Fluval 407 Canister Filter
  • Aquarium gravel and sand, such as Betta Choice Black Gravel
  • Aquarium backgrounds and ornaments
  • Aquarium cleaning equipment, including API algae scrapers for glass and acrylic tanks

Livestock shipping with a strict two-hour rule

What sets Fish Cave Aquatics apart from a pure equipment shop is that it sends live fish and coral. Each animal is inspected, packed in an insulated container and handed to a trusted courier. If something arrives dead, the dead-on-arrival policy applies, but only if you report it within two hours of signing and before the packaging has been opened or tampered with. Fish that die after going into your tank are not covered, nor are losses caused by unsuitable water or poor acclimatisation. An approved claim brings a refund or store credit, while shipping fees stay non-refundable.

How to save at Fish Cave Aquatics

The shop runs weekly deals and a countdown section of top aquarium deals, which have featured tanks, gravel, a start-up pack and a canister filter. A voucher code from this page is entered in the voucher or promo code field in the basket or at checkout; usually one code works per order, and items already reduced may be excluded. Dry goods come with a 7-day return option, so equipment bought with a code can still go back if it does not fit your set-up. If you keep other pets too, save-up.co.uk lists further Pet Supplies shops with voucher codes, such as Zooplus Voucher Codes, Northern Parrots Discount Codes, The Regal Mutt Promo Code and tails Voucher Code.

Advice from staff who keep fish themselves

Reviewers also note a good selection of fish and shrimp. If you are unsure which heater, filter or species suits your tank, the contact form lets you send your question before you order.
