Great info guys... I will keep all that in mind.
Amonya - yes, I have 2 small tang (quarter size, very small still: blue tang & 1.5 inches: yellow tang) for now. I know eventually I will need to change / upgrade my tank to a bigger tank. :)
bkv1997 - YES!!! I am changing the water every 2 weeks. My skimmer is working properly right now. Trust me... I am monitoring my tank pretty often. (Don't worry anything happen to them you know... :) )
Another question(s) for you guys...
1) how often do you feed your clown? They do eat alot along with my tang.
2) Does your clown brings food back to the anemone? I still having see that yet. I am currently feeding the anemone by myself. Any input on this?
thanks guys,
Jack
