Red Claw Blue Lobster (Cherax quadricarinatus)
23–29°C · pH 7–8.5 · 90L

Vivid red Cherax crayfish with an aggressive streak. Best in a secure species-only tank of 100 L+ at 20-26C; never with shrimp or snails.
Adult size is the maximum length this species reaches at full maturity (scientific sources). The livestock you receive will be younger and smaller — pick a size variant above for the actual shipping size. Photos are AI-enhanced, so the animal may show subtle colour or marking differences.

Maintain these water conditions for optimal health and vibrant colors
Some aquarium residents are decoration; this one is the show. Cherax red lobster is a vividly red freshwater crayfish with a temperament to match the colour — rated Aggressive on our scale, and honest about it. The right home is a secure, species-appropriate setup, usually a species-only aquarium of 100 litres or more where it can patrol the bottom, claim every inch of it and display that bold red shell without an incident report.
Day-to-day requirements are refreshingly simple for such a characterful animal. Water from 20 to 26°C suits it, with pH between 6.5 and 8.0 and hardness of 5–20 dGH — ranges most UK setups can hit without fuss. As an omnivore it takes a wide variety of foods from the substrate, and a five-year lifespan makes it a genuine long-term resident rather than a passing curiosity. Tankmates are where discipline matters. If any are attempted, the rule is blunt: only very robust, fast, non-bottom-dwelling fish too large to be caught stand a realistic chance. Small fish, slow fish, anything that lives on the bottom, shrimp, snails and — emphatically — other crayfish or lobsters must never share its water.
Understand the temperament rating and everything else falls into place. Aggressive, here, is a planning instruction rather than a warning label: this crayfish does not share the bottom, does not tolerate rivals and does not distinguish between tankmates and prey of convenience. The species-only tank is no compromise — for the Cherax red lobster it is the natural exhibit, and the 20–26°C range makes that exhibit inexpensive to run. Expect the territorial streak to sharpen further around breeding.
Think of this purchase as setting up a single-occupant exhibit: careful tankmate selection is part of the animal’s care, and the simplest selection is none at all. The pay-off is bold colour and personality that reward the dedicated setup many times over.
