Are the coralifes the same as the jbjs? I'm assuming it has the filter n the rear of the tank?.that's important...eventually u r going to want to go big..and going big requires u to get a sump, UV, better loghts , etc..the list goes on and on..for a beginner, you Dont need to worry too much about all those things.. A biocube will get u the satisfaction with out too Mich of the headache this hobby can bring ones u delve in. I wouldn't get the hqi (metal halide) because for such a small system, the temp will tlrise a lot which will be an issue in the warmer months...if u want to upgrade on the lights..go with an led pendant...just be sure to keep bio load to a minimum..which means only get fish suited for nano tanks and keep it down to 4 max..too much bio load on such a small system will give u a whole world of problems...also have plenty of live rock..and always...good flow to avoid nuisance algae...
