I am looking for something like a giant coconut because I'm re-scaping my tank and she (my female pearl gourami) likes to have a retreat when things get spooky. Any ideas? It could be suspended from the tank wall. I'm after something natural.
Coconut shells can work in some scapes but can also look really out of place in others. You can build a cave with driftwood and rocks or even look into the so called botanicals: https://blackwateruk.com
