Raw coconut shells are the hard outer layer or husk of a mature coconut fruit. They are typically brown in color and have a fibrous, woody texture.

So, for a coconut cave, firstly we have to clear out the outer uneven surface from the shell using a knife. It can’t be cleared out fully but it’ll smoothen the skin from the raw body. Otherwise, it’ll be harmful to betta fish.
