Instructables

Make a cheap and easy cave for your fish, reptile or rodent with a coconut and a few tools.

Mum recently got a BiOrb Life for an anniversary present (aww) and found ideas
for coconut caves on the net. However, to my horror, there haven't been any on Instructables.
So, we decided to rectify this with our method (which is mostly improvising with the tools at hand,
as Dad likes to take every single tool he owns with him when doing a job).

Apparently, these can be used for fish, reptiles, rodents, near about anything that's small
enough to fit. And coconuts are cheap =D

Anyway, lets get started!

Step 1: What you need:


Materials:

1 coconut

Tools:

Drill (Or a hammer and nail, if your father hasn't hidden them all)
Saw
Chisel
Sandpaper
Marker Pen

Improvise if necessary. Flat head screwdrivers make good chisels.

Step 3: Saw the coconut.


Saw the coconut to your desired size. If you do it in half, the you can make two.
How's that for economy? =P
If you can, clamp the coconut while you cut it, 'cos it makes life a lot easier and safer.

Step 5: Sand the shell.


We are putting our cave in a fish tank, so sand the shell down to make it safe for
our fishy friends. I'd probably recommend doing that in any case, so other animals
don't chew the fibres and such. Some people like to leave it though, so it's up to you.
We used a coarse grade sandpaper.

Step 6: Make the door.


Time to make the door to our cave. Draw the door in to make life easier.
We were going to use a dremel tool but found we had none big enough.
So instead we drilled holes close together near the line and knocked it
out with a hammer. A hacksaw would do the job too.
Sand the doorway to make it safe and smooth.

This is a great alternative to using pots. I never thought of this, it's a great idea! I have a couple of caves with a clump of java moss filling the empty corner of my aquarium, now I'm waiting for my chinese algae eater to go in one! Great instructable, 5*
