Very informative ... i have try copperband fish to fight the aptasia and it works like wonder. Within 2 weeks all my problem settled but the worry is with the fish, it cannot sustain and died in my tank after 2 months. And now the aptasia has make a come back... " I'm Back" hehehheh. At the moment i'm using kalw to fight it but very troublesome if the aptasia is situated at dificult spot. I have try serching for Peppermint shrimp in KL but doesnt seem to have one. How abt Singapore is the Peppermint shrimp being sold there . I'm interested to get one. Anyone selling one heheheheh
