Quick answer: Electric blue 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 Electric blue 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 We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.
Diet and molting
Crayfish are omnivorous scavengers: sinking pellets, blanched veggies, and occasional protein (bloodworm, shrimp). The key event is molting — they shed the old shell, are soft for days, and hide. Never disturb a molting crayfish; leave the eaten shell (it recycles calcium). Stable hardness and calcium support clean molts.
Why species-only wins
New keepers picture a crayfish "cleaning" a community tank; reality is the crayfish ambushes tank mates at night. Fish with long fins, slow movement, or bottom habits are especially at risk. If you want a lively, odd pet, keep one crayfish solo and enjoy its behavior — do not gamble your fish collection on its mercy.
