After Week-1 Checklist — Hermit Crabs

Week one is done. Now it’s about keeping conditions stable, supporting molting, and settling into a simple care rhythm.

1) Lock in a simple routine

Do a quick daily check: temperature, humidity, and crab activity

Keep feeding consistent (small amounts; remove anything that spoils)

Refresh water dishes as needed (fresh + saltwater)

2) Stabilize the habitat (consistency matters)

Avoid big changes to temperature/humidity

Keep the tank in a stable location (no direct sun, no drafts)

Don’t “redecorate” constantly—let them feel secure

3) Support molting (don’t disturb)

Make sure substrate stays deep and diggable

If a crab buries itself, avoid digging it up

Keep the environment steady and give privacy

4) Upgrade only where it helps

Add improvements that reduce stress and encourage natural behavior:

More hiding spots

More climbing options

Extra shells in varied sizes

5) Create a cleaning + maintenance rhythm

Spot-clean as needed (remove waste/old food)

Keep water dishes clean

Do deeper cleaning only when necessary (too much disruption can stress them)

6) Track what matters

Eating patterns

Activity level (especially at night)

Shell changes and interest in shells

Any strong odors, mold, or sudden environmental swings

7) Know when to get help

If a crab seems lethargic for an extended period, isn’t eating, or you notice unusual odor or visible issues, seek guidance quickly.

Pro tip

After week one, your biggest win is stability. Hermit crabs do best when their environment stays consistent and low-stress.
