WELCOME TO REEFLAND!

I'm sorry to hear of your loss. Not good news for the start of a New Year.

You ask a question that many people ask. It may have died from any number of reasons, or for no good reason that we know of. If you want to explore the possibilities of what may have caused the death of your fish, you will need to provide a lot more information. So if you want, you can begin by providing all the following information. (Don't take short cuts, I mean ALL the information).

How old is your tank? When did it originally cycle?
What is the size of your aquarium? Does this include the volume from the sump and any refugium?
Do you use carbon, skimmer, mechanical or other chemical filtration?.
List all specimens & sizes in the tank (fish, inverts, corals, clams, snails, crabs, shrimp, etc.).
Do you use a quarantine tank and procedure?
Foods you use and feeding schedules.
How long have you had this fish? If the fish was recently acquired (4 weeks), two more questions: Did you treat it or give it a dip before it went into the aquarium? How did you acclimate it – what procedure?
Do you use any vitamins? Fat additives? Any elemental or other additives? Please list all.
Chemistries – please give actual current numbers (Ammonia, Nitrite, Nitrate, and Phosphate at least. Plus others you have done lately). Have these numbers been changing lately?
Water parameters – please give actual numbers (pH and your pH range, salinity or sp. gr. & range, temperature range)
Do you see any of the following in your system: hair algae; micro algae; cyanobacteria growths (red slime algae); dinoflagellate (zooxanthellae) growths; brown algae; diatom growth; slimes; off-colored patches on rock or substrate that are not coralline; etc.?
Water changes (how much and how often).
What is your source water? (Tap water, RO water, DI water, RO/DI, distilled, etc.)
List what you added or taken out of your aquarium system (living, decorations, and equipment) during the past 6 weeks (or 6 weeks before you saw this in your fish)..
Maintenance schedule. What have you done lately?

. . .but because i was having problems constantly with the ph everytime i was checking i bought a buffer, so know its ok everytime!

When you say it's okay everytime, do you mean that you check it daily? What is the pH?

Thanks for the information, but it isn't enough to help you. If you want, you can proceed by providing the above information AND going back to my post and supply the information you haven't provided so far.

So far, the aquarium seems a little young to have fish in it. See: The Mature Aquarium
