After I got the coconut out of the shell all I did was boil it for about ten minutes. Still have the "cave" after seven or so years! It won't float as long as you have a hole or two in it, as you do.

I microwaved mine after removing the flesh.

Then a quick boil, I attached Anubias to mine with twine about 5 days ago.

And if you push it into the substrate it won't be floating lol
