Help Me Please

[digital_fish]

And again, because I just wung this from the beginning, I have no idea what tests I should be doing and what kind of test kit to buy. I have always done my water changes though. What would be my best option? Also, Is my yellow tang suffering in any way by being "cooped" up in a 32 G then?

Thanks for all the advise. This site is great! And I would like to assure the guy wondering if I am some fake troll account trying to do something extraordinary besides obtaining advise on fish, that I am absolutely real and that I really really do just want fish advise!!!
