The tank itself is cycled but the rock is brand new, I added some to the tank after about 6 months.How long has this tank been cycled? The rock looks pretty white.
Water parameters are good all the way across the board. I just need to know what to doWhat are ypur parameters, ammonia, etc. A quick change in levels can cause this or something bacterial maybe?
He’s the same as yesterday but my butterfly that was with him was fine last night and dead this morning what looked like his scales were falling off.

Thank you buddy!Scales falling off with a butterflyfish is often a symptom of Uronema:

Uronema / Red Band Disease - Hemdal
Red Band Syndrome in Marine Fishes: Caused by the Protozoan; Uronema sp. Jay Hemdal Introduction: This moderately common disease of certain species of marine fish is so often misdiagnosed that most aquarists apply incorrect treatment methods...www.reef2reef.com
It could also be a bacterial disease or flukes (and those would align with the cloudy eyes on the lionfish).

How do I treat it?
The vet gave me some amoxicillin capsules, will that help?How do I treat it?
Internal Uronema doesn’t have an effective treatment.
External bacterial infections are best treated in a hospital tank with a broad spectrum, gram negative antibiotic like neomycin.
Flukes can be treated in the display tank with praziquantel:

Update: lionfish died, to prevent diseases in the future of this particular tank, I vacuumed out all of the sand and water, then wiped the whole tank inside and outside with bleach concentrate, soaked all of the equipment including the heater and powerhead in bleach water for several days as well as the liverock. Is this good enough or am I missing something?
I used Clorox concentrate.

Depends on the bleach concentration - needs to be above 500 ppm for 24 hours. Rinse well and when you think it’s rinsed enough, rinse some more! I use a DPD pool chlorine test to ensure all traces of bleach is gone (no pink color develops)
100 percent bleach, no water added.I used Clorox concentrate.

It’s calcium carbonate rock from a seller on eBay.What size tank? How long has it been up and running? What kind of rock?. I put some rock in a 20 gallon once and almost killed all the fish in the tank. Guessing the rock composite stole all the oxygen. I even soaked the rock in rodi for a week then saltwater for a week.

We added a rock to our 20 gallon...only thing we did. 2 hours later we checked on it and our long nose hawkfish was dead and the 2 clowns struggling. Were the only 3 fish in the tank and only added that 1 rock. Were able to save the clowns. So the rock depleted the 02 or introduced something. We had the rock sitting in a bucket of saltwater for about 3 weeks before introducing it. SoooWhat size tank? How long has it been up and running? What kind of rock?.

Just curious why you think rocks take up O2?
What sort of rocks are you referring to?
