Hi Everyone, my tank was commissioned on 23rd June 2012. Its a second hand tank bought @ Pasar Malam. Many changes and upgrades in setup, equipment, scaping, etc along the way till now. Definitely I have faced difficulty in term of keeping livestock. Till now there was 2 catastrophes. Nearly the whole tank was wiped out. The survivors are my Blue Tang, Brown Tang, Scooter Blennies, Leopard Wrasse and Bubble Anemone. I suspect its due to Ich and parasites when I introduced in Powder Blue Tang for
