Feeding Schedule: Once daily in small portions.
🛠️ Tank Setup & Maintenance
Tank Size: At least 30 gallons per adult crayfish.

👥 Social Behavior
Territorial and aggressive – best kept singly.
May catch and eat tank mates (especially slow fish or bottom dwellers).
If kept with fish, choose only fast, top-dwelling species.
Multiple crayfish in one tank can lead to fights unless the tank is very large with lots of hiding spots.
✅ Do’s
Keep the aquarium well-covered (they escape easily).
Provide multiple shelters for security during molting.
Feed a varied diet to enhance color.
❌ Don’ts
Don’t house with small or peaceful fish.
Don’t put in planted aquariums – they will uproot or eat plants.
Don’t overcrowd with other crayfish.
⭐ Quick Tips
Hardy, colorful, and eye-catching centerpiece in aquariums.
Much better suited for a species-only tank.
A great choice if you want a large, bright, and active crayfish to watch.
