How much do marine fish cost in the UK?

Hardy damsels and clownfish start at about £18-£30, with tangs, wrasses and more specialist species running £40-£165 and up. Prices reflect that these are wild-collected or aquacultured saltwater fish. Prices on this page are live: what you see is what's in stock today.

What is the best marine fish to start with?

Captive-bred clownfish are the classic first marine fish — hardy, personable and readily available. Certain damsels are tough too, though some are aggressive. Firefish and many gobies are peaceful, attractive starter options. Begin with a couple of hardy fish, not a full stock list, while your system settles.

Do I need a reef tank to keep marine fish?

No — a fish-only or FOWLR (fish-only-with-live-rock) setup is a perfectly valid and often easier way to keep marine fish, without the intense lighting and water-chemistry demands of corals. Many stunning marine fish are best suited to fish-only systems anyway. Decide fish-only or reef before you buy livestock.

How do I acclimatise marine fish?

Slowly and carefully — marine fish are more sensitive to sudden changes than freshwater fish. Drip acclimatisation over 30-60 minutes to match temperature, salinity and pH before introducing them, ideally via a quarantine tank. Rushing acclimatisation is a common cause of losses, so take your time.

Is it safe to buy marine fish online?

Yes, with care on arrival. Each fish ships in oxygen-charged bags inside a polystyrene-insulated box, handed to a licensed live-animal courier, dispatched Tuesday-Wednesday so it never sits over a weekend. Every delivery is covered by our photo-proof live arrival guarantee — acclimatise slowly once it lands.

Frequently asked questions

Marine keeping is a step up from freshwater — it needs a stable saltwater system, correct salinity, mature live rock and patience. That said, a beginner who does the reading can absolutely start with hardy species like clownfish and damsels in a properly cycled tank. The key is getting the system stable before any fish go in.
