[Altima21136]

I have a huge problem. i got this boxfish about a week ago . he was fine . Bright yellow color . but then he turned little pale. next mooring, we woke up he was filled with bubbles all of his body. Thinking it was it we cured him for ich. using rally, and kick-ich but no luck. we then found out it may be fungus. we are using a API MELAFIX this is day 2 of melafix. he still looks awful we do not know what to do. are parameters are good . Salticity is at.024, water temp at 80 and stable. ph is 8.2 ammonia is 0 , nitrite is 0 . Any help ill post u a picture of him . as soon as i can .

A photo will be very important. Diagnosis is a hard thing to do by Internet. But like almost anyone asked an opinion, all the background information is needed, in addition to a photo. Please also provide actual readings, data, and info requested below:

How old is your tank? When did it originally cycle?
What is the size (dimensions and gallonage) of your aquarium? Does the gallonage include the volume from the sump and any refugium?
Do you use carbon, skimmer, mechanical or other chemical filtration? List all along with their maintenance.
Do you have live rock in the system? How many pounds or amount and where is it put?
Other than live rock hitchhikers, list all marine life & 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 (6 weeks or less), 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 – Do you test for Phosphate, alkalinity, calcium and magnesium? Please give actual current numbers for everything. I would like test kit test results, not dip stick results and actual numbers even if you think all is fine/okay. 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.
Maintenance schedule. What have you done lately?

I know it's a lot of info, but the more info we have the better we can help.
