Don't you think that eventually that coconut shell will rot? I know that its a very hard material but I myself would think that it would eventually rot. How about a terracotta pot wouldn't work just as well? Im new to cichlid hobby and am learning about these wonderful fishes. I would go for rocks or there are even some cool looking plastic caves that they sell in the fish stores. I try not to conciously do anyting that will harm my fish. Good luck! :fish: I would love to read more responses on this matter.
