Quick answer: Red swamp crayfish is a variety of crayfish. Everything on this page is crayfish-level guidance — we do not invent variety-specific numbers.
The care below is crayfish-level guidance from our species hub, sourced to Merck Veterinary Manual — Exotic & Laboratory Animals: Aquatic Invertebrates and RSPCA — Fish care. It applies to Red swamp crayfish exactly as it applies to every other crayfish variety. We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.
How long do crayfish live
Most aquarium crayfish live 2–5 years; Australian yabbies (Cherax) can reach 5–6. Longevity suffers from soft-water molting failure (they need calcium and stable hardness), poor filtration (they are messy), and injuries from tank mates. A species-only tank with good minerals keeps them healthy.
Tank and the predator reality
A single crayfish needs a 20-gal (75 L) tank with hiding caves (PVC, rockwork) and a secure lid — they climb and escape. Keep them alone or with fast, top-dwelling fish only; slow or bottom fish become food. Provide a sand or smooth substrate for digging. Strong filtration handles their waste.
