hermitcrab is right. Do not over-care your fish too much. This is one thing i learn as a reefer. Sometimes, the more u care, the more detrimental to their health. Last time i itchy hands, every few days always change water, rearrange rockwork, severely over feed, catch them out etc etc. RUBBISH. let your fish settle down, enjoy their new home. Do what is right for the fish, not so much what is right for you. Example, if your favourite aquascape has NO holes and caves for your fishes to hide, re-do it, even if you like it alot. This is just an example. Dont worry wei bro. We are all here to help you. You will be successful in your hobby one day. For now, just get an ammonia test kit first. Very important.
