new tank, need help
hey all, i am VERY new to this and was wondering if there was a checklist of some sort that lists everything one needs to maintain a SW tank. I put in a custom 55g and already have live rock, a pair of firefish and a radiant wrasse (which i think is dying). A friend put in everything but i want to start managing it myself. Any helpful threads would great as i was not able to find any in a search. Thanks.
Here is pic of the tank:
