• Substrate: Sand or gravel – they dig burrows.

• Water Changes: 25–30% weekly.

👥 Social Behavior

• Aggressive and territorial; best kept alone.

• May attack or eat tank mates, especially slow fish or bottom dwellers.

• If keeping multiple, use a large tank with plenty of hiding spaces.

✅ Do’s

• Use a secure lid – they climb and escape easily.

• Provide hiding spots for molting safety.

• Feed a varied diet to keep their color bright and healthy.

❌ Don’ts

• Don’t keep with small or slow-moving fish (they will be hunted).

• Don’t overcrowd – fights will occur.

• Avoid live plants (they will dig them up or eat them).

• Better suited for a species-only tank or with fast, upper-level fish.

• Great choice for crayfish enthusiasts, but not ideal for planted or peaceful community tanks.
