How to Make a Hermit Crab Shell

Hermit crabs need new shells as they grow. Shells provide protection and security for hermit crabs, but they can also be a fashion statement for your pet. One of the simplest ways to customize your hermit crab's shell is with a painted design or color scheme.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• "Blank" shell
• Pot for boiling water
• Paper towels
• Non-toxic craft paint
• Paintbrushes

1. Select the right size shell for your hermit crab. The opening should be about 1/4 inch for a small crab and 1 1/2 to 2 inches for a larger crab. The crab should be able to withdraw completely into the shell and cover the opening with its large claw.

2. Make sure there are no rough spots around the opening or inside the shell. Reject any shells that have cracks, since crabs need to keep a bit of moisture inside their homes. Crabs also seem to prefer shells with smooth mother of pearl linings.

3. Boil the shell in water for at least 5 minutes. Drain and dry it with a paper towel. Allow the shell to cool completely.

4. Decide on a design for your shell. Stay simple with a solid color in a primary, metallic or neon shade, or go bold with stripes or polka dots. Opt for a sports theme---paint your favorite team's logo or a basketball or other ball design. Take ideas from nature---include a lady bug, daisy or other flower or a rainbow---or paint your shell with your favorite cartoon character or superhero design.

5. Let the shell dry completely before placing it in your hermit crab's habitat. Make sure the paint is fully adhered to the shell; otherwise, your hermit crab might ingest paint chips.

Tips & Warnings

• Because hermit crabs can be choosy about their shells, provide them with a variety of choices. Avoid using glitter, stickers or other craft items that might fall off the shell.
• Do not try to decorate a shell if the hermit crab is inside. Never force a hermit crab out of its shell. Don't paint the inside of the shell.

on 9/10/2009 Decorating shells for you hermit crabs is childish and a sign of a badly informed owner. Paints, jewels, and makers are toxic to the crabs. It will chip off, it will be eaten by the crab.
