Hi and congrats on starting your tank cycle!!
I think your invert list sounds great, don't count out the skunk cleaner shrimp though, I have a pair in my 29 gallon. If you want sexies wait until you have a reef set-up going and are fully stocked fish wise. Just a tip....save some shrimp till the end cause one day you will be fully stocked fish wise and will not want to leave the LFS empty handed, this is when adding different shrimp species gets
really exciting IMO.
The size of your QT (2.5 gallons) jumped out at me- will be super, super tough to keep a fish in there and parameters stable, but you probably are already doing major water changes with the chromis and know this. :joy: As for the lighting I am not too sure since I only have power compacts on both my tanks, but where the one you ordered has higher wattage overall it may be the better choice. But that is just a guess on my part, hope somebody else chimes in here to correct me!
There should be a locked topic on lighting somewhere on this site that would maybe help you decide.
