I will have to adopt the same tone with you, Nicholas.
You're not taking a hold of yourself. Please... control yourself.
Your tank doesn't look at all stable and your constant rate of fish replenishment is a clear sign that something is wrong somewhere... and stop blaming it on your humbug damsel.
You should stop now, take a break... READ UP on BASIC reefkeeping first. You don't even know what is a metal halide!
You buy livestock and you don't even know what they need.
Eg. Your seapen needs a deep sandbed to root itself in. A scattering of sand is also not going to provide enough food for your goldenhead/bluecheeked gobies.
What brand of test kits are you using... and how often do you test your water parameters since you're stocking up so quickly within this short time. Your ammonia, nitrite levels may spike up and down, causing stress to your tank inhabitants.
Can you try holding off buying any more fishes until your tank stabilizes?
A reef tank should be a STABLE environment, providing conditions where its not just survivable for the inhabitants but GOOD.
Do read up more and lock up your wallet (or your dad's).
If you want to be respected as a reefkeeper, be responsible enough to accept good advice from your fellow hobbyists here in SRC.
My 2 cents,
